so i went geocaching the other day
if you don't know what that is, it's basically a worldwide treasure hunt where you find other people's "caches" with the aid of a handheld gps and then sign their log book or trade out for something someone else left in the "cache"
it's pretty fun and some are hidden in really cool locations
if you want to check it out go to www.geocaching.com
there are over 500,000 in the world so chances are there are some close to you
