Not the East Coast, but here in Louisiana I'm lucky to live near the Tammany Trace, a 30-mile Rails-to-Trails dedicated bike path. Rode 50 miles round trip Saturday. To my knowledge it's the only dedicated bike path in Louisiana, except for a far inferior levee path down in Jefferson.

I look at some of these discussions about car/bike crashes and dealing with drivers, and I feel soooooooooo lucky I don't have to deal with that. Especially since in Louisiana we have a law that motorists have to try to run down cylists and pedestrians. It's the law.
