Oh wow! Okay, let me explain, you might like it, especially if you travel a lot. So you go on GPS treasure hunts to find little boxes hidden in secret places. They include... well, toy cars, collectible coins, pins, stickers, artsy things, etc. and most importantly, a logbook! What you do is look them up on a website like this, find them, log your find, and do the same online. If you want you're welcome to take something as a souvenir or pass it on into the next cache you find. And since you like to blog, you're always welcome to document your search. The rules are: trade equal or above (so please don't take the 1882 silver dollar for leaving a bottle cap), and don't reveal the hiding spot of the cache. It's a game, so please think about those who come after you. For more info visit the link. :-)
