Geocaching - fun!

Okay, I admit it! Now I've been bitten by this bizarre hobby - geocaching. Found my two first two tonight (with a tiny bit of help from Dagim...) You get some coordinates, find something at that spot, leave a mark, then write a log. It's like orienteering, just slightly bigger scale (having a car is an advantage...). Now I need a bike and a GPS to start with! Then I'll be off to the adventures of geocaching all by myself!
