Thanks for all of the comments everyone.
Eloise, I will be getting ahold of the rider and plan to send him a couple of 8x10s. He earned em!
John, I know what you mean. I've lowsided and that hurts enough for my tastes. Can't even imagine how bad hitting that track hurt this time. As for "How" its the exit of a long sweeper and there is a bit of a dip. He grabbed too much throttle just as he hit the dip and just slid out. I thought he was gonna lowside it but the next thing I know the bike is swapping ends and he is flying thru the air.
Also, I found out today that he broke his collar bone... OUCH! Not bad though considering that he probably flew 60-70' through the air.
Mike
p.s. still waiting for an update on the guy who was medevac'd. Please keep him in your thoughts and prayers.
