You're right, mac, there's a slim chance that you could crash and wind up unconscious. However, on day 1 of the MS last year, I witnessed a guy have a front tire blowout, go over the front end and hit his face on the pavement. He was out cold and seriously injured - had to be Lifeflighted out.
Anyone actually call the MS Society and get the official word on this?
Sorry you can't make it, Dr. Nate. Good luck on the gray transfer guys. I say if you want to ride and agree to raise the $$ in someone's place, you should be able to go.
