Not exactly hiking trails, but it's nice to see the tourism site put together some ideas for walks through the city. I would probably add the Little Sugar Creek Greenway from Park Road Shopping Center up to Midtown.
Any other good walks to be had in town?
Dang, I lived over that way as a kid and didn't realize there was an airport over there. The first I heard about it was when they were shutting down to sell the land.
