Camping along the BRP
I'd also like to recomend both Willville motorcycle campground on rt.58 just west of Meadows of Dan Va. and the Blue Ridge motorcycle campground off of rt.276 in NC as great places to camp when riding the Blue Ridge Parkway. They are run by great folks who cater to motorcycle riders and both are very great places to relax after the days ride. I enjoy camping with other riders and hearing the stories that are shared around the fire at night.
I think KOA's have priced themselves way too high for what you get for the money. 30+ dollars a night for a spot of grass... really..
