That's a nice run, Barry. I've done it twice. Although I think you're going to miss the best part of the BRP. The 100 miles from there to Asheville is, in my opinion, the nicest part. I'm jealous!
Hey, are they still doing Supermoto races at the Go-kart track in Chantilly?
Oh... I'm VERY familiar with BRP from Boone to Asheville. We may very well hit all of that while we are there. Although within 20 miles of Boone/Blowing Rock is crazy good riding.
Supermoto starts in October IIRC at AllSports GP in Sterling.
www.supermotojunkie.com has the full schedule. You should come out and spectate. You can give it a try on the TTR if you want. Crazy good fun.
