Having hosted several events for other groups out of Canaan Valley, I can say it is a good area to ride. However, there are some limitations. For one, nice dining options other than the lodge are just about non-existent. Gas stations are small and far between. Fueling up 40 bikes could take forever at 4 hole stations that don't take plastic. Just something to consider.
For WV.. I think Fayetteville or Beckley, WV makes a excellent location. Good riding, excellent fun roads, and Beckley is not far away for those who want to do shopping etc. Issue would be finding motel and camping options close together.
