Adam, you better make a shaded version of the Starbucks vs. Wal-Mart map!
Anyway, here are some random maps I made (and posted) a while ago:
Cremated vs. not cremated

Virginia is the only thing that strikes me as strange, which Costco won 14-13. Delaware is a tie. None in D.C. Vermont had one Costco and nothing else, while Rhode Island had one Sam's Club and nothing else.
Target (red) vs. Wal-Mart (blue)
Wal-Mart vs. Target. Didn't think about K-Mart... But then again there are lot of stores I could probably include, like Kroger and all the chains it owns.
McDonalds (blue) vs. Starbucks (red), AR at 89% McD and WA at 69% Sbux.
