I'm In the USAF, stationed in Great Falls, MT and I was introduced to caching around 2004. My first GPS was a Magellan sportrak map. I was going to take my GPS on my next deployment with a list of the caches in the area, but I forgot both and with how busy we were over there, forgot all about caching until I read about it on an RV forum I frequent: www.popupportal.com. I told my kids about it and they were like, "yeah, let's go!" Now they ask me every day if we're going and get real disappointed if we don't. All 4 have their own caching bag with trade items and "Found It" log book; They're also saving up their money to get their own GPS.
