A friend of mine put up a map of all the places she'd visited. I thought I'd do the same. Mine isn't nearly as impressive as hers, but here it is...
I only included states that I have actually done something in (not just driven through).

Outside of the U.S., I've only been to Canada and the Bahamas, so my world map is even less impressive. I'm not even going to bother posting something like that.
