World66 is a site that you can keep track of places that you've been in the United States or which countries you've visited around the world. In my family we use to have coloring book type maps of the US that we kept track of this type of thing, but this makes it a lot easier.

World

Yeah, just three other countries at this point (Canada, France, Mexico). I plan on increasing this number in the not so distant future.

United States

I've spent the night in all but 5 (MS, MO, NJ, OK, and TX). I'll probably be changing that about two (MO and TX), as I have friends that live in both places and hope to get a chance to visit them in the near future.
