We've been doing GeoCaching for a number of years, enjoying learning about new parks and finding Geocaches on our trips. Earlier this year we created our own Geocache near our house and placed a Travel Bug in it - MoonBoy. His goal was to view a space shuttle launch and to someday travel on a Space Shuttle.
Amazingly, he's made his first goal and was an observer to this weekend's launch of STS. This is totally cool! Here are the photos on the GeoCache site
