Tim I love your idea but even if there are 10 others posting from Jacksonville, I can guarantee you I'm the only one from 32211 - it's a big big city both geographically and populatively.

Still, I'd love to see the trends of geography: what does the AC do to our AZ folks? How severe is the MPG decrease each rainy season in WA?

Jason, I know in some cases it would almost be silly since it's half a globe from one side of TX to the other, or topographically opposite from the Bay Area to San Diego, but would it be possible to have a breakdown by state? Some data would be better than none, and the smaller or more like-climated a state is, the more accurate that data would be regardless of ZIP. AND you'd only be responsible for creating 50 categories, most of which would provide adequate sample size even right now. What do you think?
