I live in Wilmington, NC and while there are a good number of multi-use paths/bike lanes for a city in the South, it's still not very friendly for bikes. I think part of the reason is that neighborhoods are so separated from each other (subdivisions) so there are few shortcuts/lower traffic roads forcing you to have to bike on major roads which makes it dangerous. Also people here swear by their cars and there aren't many bikers so they don't know how to deal with them. I've also noticed that many of the bikers around here aren't aware of the proper rules - I saw somebody today biking the wrong way down a major urban street! (again it's a car-driven society around here) I work for the DOT but I don't have any say in the design of some of these roads or planning - wish I did but for now I'm just figuring out asphalt calculations
