Looks like I'll be in Chattanooga for two weeks working on a project. I'll have the weekend between the two weeks off. I'm looking for some input for a hike. I was thinking about heading to a trail Saturday morning, hike out, or do a loop, stay one night (Saturday night), and be back at the truck Sunday around lunchtime. Any suggestions on trails within an hour or two of Chattanooga? Will be the first two weeks of January, and I have a 20 degree bag, will that be enough?
