Does this count as blogging? I’m not sure.
I just discovered the world of geocaching. Check out www.geocaching.com for more info, but basically it is scavenger hunting with a GPS unit. You are given coordinates and clues, you go the location and look around for the “cache.” There is generally a log book you sign and may be goodies inside – if you take something you leave something. I’ve found 5 so far and I think I’m addicted.
