Hi, my friend and I just joined geocaching (separeately, he's in Florida) and subsequently Groundspeak. I don't understand the travel bug at all. The more I read the more confuzzled I get. does this thing actually exist? is it just "posted?" consider me confused. Also I will be going from Monterey,CA to Athens,Greece at the end of the month.. I'd love to help a little guy see the world.
