Can I throw in a vote for Wilmington, NC? Small-ish city, but we have killer beaches that are generally easier to get to by bike than car when the tourists are in town. I've been commuting here for a year now after moving from Denver, CO, and yes it is certainly different than a big city, but in a good way. The city has listened to the small but vocal cycling community and is making improvements to the infrastructure to include protected MUPs, designated bike routes, and increased signage.
