How far should we expect to get?
We will be travelling from around Gettysburg, PA on Sat., Nov. 29, as far south as we can while also seeing at least some of Skyline Drive. My goal is to get within a few hours of Great Smoky Mountain NP by Saturday evening, so Sunday we can enjoy as much of GSMNP as possible (as well as all day Monday).
My thoughts are to leave the Gettysburg area early Saturday morning, drive at least some of Shenandoah NP/Skyline Drive from Front Royal, and then get on I-81 to head south. It's hard to tell from my map how many opportunities there are to bail out of the park and head west to pick up the interstate. Should we just go to Thornton Gap (around Mile 30) and take 211 via Luray? Are the caverns worth seeing? Or should we continue down to, say, Rte 33 at Swift Run Gap (around Mile 65)?
I'd like to keep our total driving time to around 7 or 8 hours. That would allow us to do some hiking, picnicking, etc. Thanksgiving weekend traffic and weather conditions notwithstanding, how far south should we expect to get? Ideally I'd like to get at least as far as Roanoke. Is this at all realistic? Any other suggestions? Thanks!
