Just my $.02. We were there on a Saturday afternoon during the RA Rally at Asheville (Biltmore) (my 4th time since 1994). It was beyond crazy. We saw three wrecks involving 1 fatality. One head-on between 2 bikes, one rear-end with a pickup, and one lost it and flew off the cliff, and this was just during the time we rode up to the summit. We declined to ride back down because the cops and EMT's had traffic held up. If you like a mix of semi's, pickups hauling boats, tourists in cages, Harley's trying to be CBR's, Crotch rockets trying to set land speed records while trying to pass everyone else, then "The Dragon" is for you. Just remember, it bites. Don't be fooled. It is like this every weekend in the Summer. In fact the odds of a vicious wreck are so good, that there are film crews from squid websites at many turns waiting for you to turn into road pizza. Consider yourself warned.
End of rant.
