Florida to Townsend, TN

You are not afraid of Atlanta but want to avoid Chattanooga? I drive this route quite frequently going north and have never had a problem. However, to address your question, if you go the way you suggest, you will have a lot of traffic on 441, some of it is two-lane and you will have to slow down and stop for every traffic light in every town, and spend a lot of time getting through the Pigeon Forge area. Also there is "no good time" to go north through Atlanta in I-75 unless you go through about 2:00 a.m.. It's not the scenic route either - very bland and boring. Once you get there, though, it's very nice.
