by Bernhard Baumgartner , Omicron, Austria Art, Sport & Entertainment hobby 94 The Challenges of Geocaching I was totally stunned when I suddenly realized how many castles and medieval ruins are located around my home. Geocaching can be a wonderful experience, so why not try it yourself? It is great fun and I am sure you will enjoy it. But be careful! - It is highly addictive. PAC.WINTER.2009 Bernhard Baumgartner, solving a geocaching riddle Geocaching –the beginning It all started on St. Nicholas Evening about a year ago. I was sitting in a nice restaurant in Rankweil, a village in Western Austria. Together with friends and former workmates I had a great time reflecting on old stories and experiences. After a while Martin, a good friend of mine, mentioned that he is actually working on a GPS receiver – a personal creation. “Well, what do you need this thing for“, I asked him. “Well, Geocaching”, he answered. “Geo.. what?”. Well, this is how I got to know about Geocaching, a great sport and fun for the whole family. In the mean time my kids, my wife and I have also become Geocachers. But be careful “Geocaching is very addictive, so don't start”. So you might want to stop reading this article now. OK, you decided to continue reading. Which is great, because Geocaching is one of the greatest things you can spend every free minute on. It is a GPS Treasure Hunt, where you use GPS receivers and other gear to detect Treasures, mostly small plastic containers, hidden by other Geocachers. I do not plan to go into a lot of details about the principle behind Geocaching in this article. My plan is to mainly share the experiences of our Cacherfamily with you. But I think some basic explanations might be helpful for those of you not familiar with Geocaching. Introduction Each Geocache, most of the time just referred to as Cache, needs to be published on a web page. The most famous one is www.geocaching. com but there are also other pages such as www.navicache.com. Every registered user of a Geocaching page can download or print out the cache listing and start his search. There are several types of Geocaches but the most used ones are Traditionals, Multi-Caches and Mystery-Caches. The Cache listing for a traditional cache contains the exact GPS coordinates where the Geocache is 95 hidden, as well as a description of the location the cache is hidden. Traditional Caches are mostly used to show a beautiful spot in nature, a great building or any other place of interest to the community. A Multi-Cache listing contains the coordinates' starting point and several way points that need to be visited one after another. At each way point data needs to be collected which is needed to either calculate the next way point, or the coordinates of the hiding place of the Final Cache. The purpose of MultiCaches is for example to introduce a nice town or an interesting hike to a Geocacher. A Mystery cache listing usually consists of a riddle, which needs to be solved to calculate the coordinates of a hiding place, or of a place where the next hint is hidden. Mystery-Caches can be used to introduce a historic person, special knowledge or a specific field of science. But most of the time it's just a great riddle, which you are eager to solve especially if you know the Geocacher who has hidden the Mystery Cache. More details: The cache sizes vary from very small (size of a lithium battery) to large (old military boxes). For each cache a difficulty rating and a terrain rating is manda- tory, this helps the persons looking for a cache to prepare themselves for the Cache hunt. While the difficulty rating mainly indicates how difficult it is to find a cache when you arrive at a cache location, the terrain rating indicates how difficult it is to get to the cache. While a terrain 1 Cache can be usually reached via a walk or drive on paved roads, a terrain 5 cache usually requires special climbing, hiking or diving gear in combination with good endurance of the Cacher. For example there are caches on many mountain tops around the world - on the Uhuru Peak of the Kilimanjaro a Geocache (Identification Number GC10CTQ) with the terrain rating five is hidden at 5894m above sea level. Each Geocache contains a logbook in which the finder logs the date and time of his find together with his Cacher Nickname (My Geocacher Nickname is Baumi_B) and a short message to the owner. Further on most caches of the size small, regular and large contain small trade items. Especially kids like to trade small toys. Back at home you log your find online on www.geocaching.com. In the online log people usually share the experiences they had looking for the cache and sometimes even photos with the community. I like Geocaching, because it is a hobby for the entire family and you can practice it nearly everywhere. 2 Caches come in different shapes and sizes At the time this article was written I had logged 527 caches which brings me to rank 144 in Austria, rank 5634 in Europe and rank 18042 in the world. In general, Geocaching is not an expensive hobby. All you need to start is The adventures began... Okay, these explanations must do it for the moment. Let's go back to the start of my Geocaching adventures. After I returned home from the St. Nichlolas get together, I could not get this Geocaching thing out of my mind – so I started my computer and visited www.geocaching.com. And after a few minutes I found out that there were about 100 Geocaches hidden within a radius of 5 miles around my home. If you look up your place of living on a cache page I am pretty sure that you will find out that you have passed dozens of cache hiding places without knowing it. Amazed by the high number of caches I ordered myself a cheap hand held outdoor GPS receiver the same night. I did go for a cheap receiver since I was not sure if I would stick to my new hobby or not. Well, I did not know how addictive Geocaching is at that point in time. The next morning I told my kids and my wife about the new sport. “Sport?” my wife smiled, “this doesn't sound like a sport to me”. Well she changed her mind after the first few caching tours. Geocaching is a sport but a scalable one, because you decide for yourself on a terrain and tour length when you plan your Geocaching trip. Here in the Austrian Alps it is maybe a little bit more of a sport than in urban areas where you can reach more or less every cache location nearby by car. While my wife was skeptical, my kids got excited. Looking for treasures in the woods and mountains sounded quite interesting to them and they started to bug me on PAC.WINTER.2009 a hand held GPS receiver and a computer with access to the Internet. But to be serious, you will need some money for walkie-talkies and tons of other outdoor gear. But as long as you have a set of rechargeable batteries, all you need now and then is the cost of transportation to get you near Geocaches. Art, Sport & Entertainment hobby 96 a daily basis to take them out treasure hunting as soon as my ordered GPS receiver arrived. A few days later my GPS was delivered and I searched and found my first cache “Dornbirn central” (GCPV9H) - in the middle of the night close to the church of my birth town. From that point an interesting change happened in my life. My wife is a nurse and therefore she works weekends quite frequently and it is my task to entertain our kids during the weekend. When I would tell my kids that we would go for a walk they were always quite bored. But since we are Geocaching, they are really eager to go out and search for treasures. Addictive & inspiring hobby Within my first month of Geocaching I found about 40 Geocaches and my wife also got infected with Geocaching and started her own Geocaching account under the nick name GM70. GM is short for Gangster-Maggy and the way she got her nickname is quite interesting. It was late at night on January 12th, a Saturday evening, when my wife and I drove home from a nice evening with friends, when we had the idea to quickly search a cache at the local Cineplexx (GC17AQ6). So we parked our car and started to look for the cache. The cache is categorized as a micro. Micros are usually 35mm film canisters that just contain a small logbook and so there are many potential hiding places for a small film container at and around a building. Despite the late time, there were many Muggles around. OK, another thing to mention: Muggles are all people who are not active Geocachers. And it is a rule in the geocaching community that you never tell your real motives when a Muggle asks you what you are doing, while you are looking for a Cache. This rule adds a lot of fun to Geocaching and helps to avoid that a cache is muggled (= stolen or disposed as trash). To avoid the attention of any Muggles we operated in Stealth mode. But my wife must have overacted answering virtual calls on a mobile phone every minute while standing close to parked cars. I had some reception problems due to reflections caused by the big Cineplex building therefore I moved away from the building to get a better signal. At this very moment my wife walked up to me and told me that a dark car is following her around the parking lot. Suddenly the dark car picked up speed, rushed in our direction and stopped with smoking tires. Blue lights went on and two police officers stepped out of the if you are active, you have to travel further to find Geocaches you have not logged so far ! car. The officers immediately started to question us. They wanted to know why we are hanging around the parking lot, and why my wife was making suspicious phone calls close to parked cars. Well, I really would like to tell you that despite severe questioning I obeyed the muggle rule and kept my mouth shut. But unfortunately I have to admit that I cracked down within the first 5 milliseconds. I told the cops everything about Geocaching and showed them my GPS receiver. And now a very funny thing happened, the cops where really interested. They asked a lot of questions about my Hobby. First I thought that they are just question- 3 Geocatching challenges and unforgettable experiences... PAC.WINTER.2009 by Bernhard Baumgartner , Omicron, Austria 97 ing us. Therefore I offered them more than once to show them my ID – but they were only interested in Geocaching. After half an hour of relaxed small talk the police officers wished us good luck for the search and left. Since the officers got suspicious due to the intended stealth mode of my wife, I nicknamed her Gangster-Maggy and she decided to use the abbreviation GM70 as her nickname at www.geocaching.com. Another great thing to do are night caches. Night Caches should only be logged at night. To ensure that these caches are only searched at night, the Cache owners usually only provide a starting point from where you have to find a reflector with your pocket torch. As soon as you have located the reflector you walk there and start from your new position to look for the next reflector and so on and so on. For sure you have to solve riddles on the way to calculate new way points. The owner of a night cache in Switzerland mounted a laser pointer below a pedestrian bridge. If you press the laser pointer’s button the laser beam marks a telephone pole on the other side of a river where you can find the coordinates for the next way point. But for sure the most romantic experience for me was when my wife and I celebrated our wedding anniversary by seeking a night cache in the Ötztaler Alpen. My wife picked the hotel for our stay due to the high number of the caches hidden in the closer vicinity. Immediately after arriving at the hotel we asked the receptionist for the trail over the Ochsenkopf, which is a small mountain close to Obergurgl in Tyrol. The receptionist answered that there is no trail over the Ochsenkopf. Well there is a trail - clearly marked with bright reflectors. And so my wife and I walked through the dark forest to find a cache called “The key to Happiness” (GC15P4N). A brief retrospective It is strange how your perspective changes when you start Geocaching. I can remember that I really hated it when I had to participate in night marches and maneuvers during my military service time. Today I enjoy to meet with Cacher-Friends and to hike through the woods at night for hours just for the pleasure of logging a night cache. If you like motorbike riding in the mountains you possibly should keep your eyes open for so called MoCaches. MoCaches are Geocaches which are hidden near great motorbike routes or on passes. In the Swiss Alps alone there are more than 100 hidden MoCaches that just wait to be discovered by motor bikers. So you might ask yourself, who is hiding all these caches? Are there people that are paid for hiding Geocaches?. And this is the great thing - all active Geocaches are hidden by Geocachers. In fact every Geocacher is allowed to hide a Cache as long as he obeys some simple rules available on the Geocaching Webpage. Before a cache listing is published on the web a voluntary reviewer checks if all rules are fulfilled. At the time this article was written exactly 698,176 active Geocaches were listed on www. geocaching.com – all of them hidden by Geocachers. For sure Geocachers are interested to meet each other, therefore regional Geocaching events are organized on a regular basis. Such events are good opportunities to exchange tips and tricks, as well as discussing difficult or extraordinary Geocaches. Geocaching Events are usually visited by people from all ages, singles, groups, teams and families with kids. Some events are spiced up with Geocaching competitions. Since most Cache Owners hide their caches at beautiful locations or at places of public interest, it is very likely that you got to see much cooler locations than the ones described in your tourist’s guidebook. Bernhard Baumgartner (GC - Nickname: Baumi_B) was born in 1971. He lives together with his wife and two kids in the Western part of the Austrian Alps. Bernhard holds a degree in electronics and marketing and works for OMICRON Lab, a new business division of OMICRON electronics. Prior to this assignment he worked as R & D engineer and Product manager in the terrestrial broadcast business for 15 years. Bernhard is in the lucky position that his family shares his passion for Geocaching. 4 More challenges & fun 5 You can end up at fun places, you never intended to visit Since most Cache Owners hide their caches at beautiful locations or at places of public interest, it is very likely that you got to see much cooler locations than the ones described in your tourist’s guidebook.
