Three things:
I feel like there should be separate shades for places that people will go to in the future and places they want to go to but have no actual plans to do so.
Say you wanted to make one of these for yourself instead of AH.com as a whole. Where would it go? I would put it here, but perhaps there should be a separate thread.
I live in California so that should be changed to the darkest shade. I'd do it myself but it's pretty late here and I probably should have gone to bed a while ago.
