this Meetup is announced to the Group
Okay, so geocaching is an outdoor activity using a GPS and a website to send you on a search for hidden caches out there in the woods/marsh/anywhere undeveloped. There's even adventures where you go from one cache to the next by solving problems at each waypoint that tells you where to go next.
Within each cache, you find all kinds of trinkets, a log book, special geocaching metal bugs that can be tracked all over the world (by people taking it and putting it in another cache somewhere else), and it's all kinds of fun! You track your progress online, showing which caches you've found, you can make your own caches, you can team up with friends, you can tag different caches as being cool or exciting or whatever. You can even do it using an iPhone via the app store's Geocaching App. Thought it would be a cool adventure to go on as a group!
