I am going to be driving with a friend to Nashville in the middle of March. We'll be passing near the southern terminus of the Trail. I'd like to take the opportunity to complete a overnight hike that will allow me to get some idea of how I and my gear will perform when I take off in earnest in the beginning of April. I need advice from experienced AT hikers on a good drop off and pick up point(s) that will allow me to get a vigorous workout and test my gear in a short time. I'd like to spend more time on the Trail but I can't. It's an opportunity I cannot pass up. I'm 58, and an experienced flatland hiker. (I've been training on every hill and long stairway in North Central Florida.) I also have better than average outdoor skills. Thank you in advance for your replies.
