A fun marketing idea from Honest Tea: they set up unmanned kiosks in 30 cities and asked people to pay $1 per bottle of Honest Tea on the honor system. They published the rankings online.
The top three places were Oakland, Salt Lake City, and Boulder, with the first two scoring 100% (I have no idea of the sample size) and Boulder with 99%. The bottom 3 out of 75 places were S. Chicago fans at 82% (what are S. Chicago fans?), Los Angeles (79%), and Brooklyn in last place with a distant 61%.
