wish i was going...have fun! and keep it in your lane. bring back good pics. if you're filming from inside the car (esp a camera mounted inside), use a wide-angle lens, which provides much better results and a more realistic view.
if the harleys are there, you might be best served exploring most of the other roads, some of which are as good or better. i was there w/ the Subarus one year...fantastic time as long as everyone acts like a grownup. we went over the dragon on the way in...at 1am in the pouring rain. not good times...bad times.
we stayed at a place closer...fontana village, i think? a craphole, but closer than robbinsville. there's also a biker motel right at the end of the road on the NC side....
