Hey Vic, the Skyline Drive and the BlueRidge Pkwy is basically a highway that is cut through the tops of the mountains and goes for over 1000 miles. The highest point that we road was at 6800 feet. You are pretty well looking down at the other mountains. There's tunnels cut into the mountains that you ride through that I liked a lot.
No worries about big trucks, you won't find any up there, just the occasional RV enjoying the scenery.
As for my bike this winter, I to do not ride. I am almost in the process of installing a HyperCharger I bought, along with a carb stage 3 re-jet, progressive front fork springs, and the list goes on.
Here's a link to my photo's from the trip. SuperBoy_X's Library | Photobucket
