I landed on this site and thought it was pretty cool. My grandmother used to have a map like this on her refrigerator and it was nearly all red. I admired it as a kid, and now I have my own thanks to the internets . It maps out the states you've been to for all to see. There's also one for countries as well, for all you world travelers out there.

Here's my map. It's kind of funny because you can see my weird road trips that mysteriously skip states entirely. Like from New York–California where we skipped Indiana for no explicable reason. Same goes for the Carolinas on my way to Alabama, and Connecticut and Massachusetts on my way to Vermont and New Hampshire. Weird!

My countries one is nowhere near as impressive, so I won't pretend that it is:
