Does anyone "play" this little outdoor scavenger hunt game? My buddy moved up to Cleveland, TN close to me, and he's big into it, and we took my 2 girls out the other day and they love it. Hopefully, it keeps them off the Wii...but does anyone here do it?

I like it to better my use with the GPS. You go to geocaching.com and register, then go find places near where you are, find the cache, and sign the log book that you found it. Pretty cool stuff. We plan to hide some cache's too.

Anyways, just thought I'd ask.
