A friend of mine mentioned having a mental map of the states she'd visited. I thought it might be interesting to make an actual one. Dark green are places I've lived. Light green are places I've visited.
My general rules are that to count a place, I must have slept and eaten there. Airports don't count.
Good free maps used to be hard to find, but here's a site that has some good ones: d-maps.com

I suspect I've been to Vermont and Delaware, but I'm not sure.
