Blueridge parkway is a great ride. Fantastic roads everywhere around the blueridge, it is hard to find a bad road.
actual sign on the blueridge
I am in Bawlmer as well and a ride to the intersection of the blueridge and 77 is a long one day trip. Continue to the end if you choose, but I would suggest trying the sideroads after Asheville and spending the night then continue to the end and of course go to Deals Gap.
for the return trip I would suggest going west and taking some roads in WV to avoid double trackin over the same roads
If you need more info, maps etc. pm me and we could meet for a few beers and I will fill you in with the details.
