I was looking at the hit count on this site. Seeing as almost all of them are from Dave Barry's Blog, I say Thanks Dave! I also noted that there seems to be a lack in 6 states. I have gotten at least one hit from every single state except Lousiana, Idaho, Wyoming, 2 States next to Illinois, and Rhode Island (I think). I am not certain on some of them, because I don't know the Eastern States very well.
Anyway, as a game, I think it would be fun to try to complete the board. So if you know someone from one of the outlined states, then make sure to ask them to see this site. I will try to make it more specific as soon as I can.
