Philly made the list, eh? Woo-Hoo!! Interesting...as I cringe every time I see a courier on the roads in the city. I'm sure it's ranked because of the areas around the city...great for riding.

To add my own opinion to the list...I would have to say Fort Collins, CO. What a great city and so bike friendly it's amazing. Literally a bike rack on every corner and 15 in between!! Everyone rides their bikes around town, and you always see pacelines heading out of town toward the mountains. My sister lives there, and I would love to spend a month out there training!
