When I was stationed at Wright Patterson AFB, there was a big group of people that had formed a riding club that did mostly Saturday rides out of Xenia. They also did birthday rides (everyone rides the age of the birthday person), centuries and in the Spring and Fall would put together 2 and 3 day trips. If you are interested, shoot me a PM and I will hook you up. They are the victory riders and wear bright yellow and black jerseys with aircraft on the front.
