A race at Red Bud each year for Vet riders. They have age groups from 18 on up with A,B,C and D classes in most of them.
Its a laid back fun time, there is a group of us that head up and have fun. Probably 50 riders or more that are on hear go. Usually our group there are 20 or so. Friday is practice sessions and sat is the race day.
Sharc or Rocketrobin need to chime in on it, they are much better at describing events in a colorful way than I am.
