Here's the info I have so far.
Tinker Air Force Base Sun Run Car and Motorcycle Show
40 classes to compete in. 1st place trophy awarded in each class and the commander will present $100.00 cash to his favorite. $25.00 entry fee, each participant receives a t-shirt and dash plaque. All motorcycle participants must wear helmet, vest, long sleeve shirts. Follow the signs off I-40 and on 29th street to food, fun and entertainment. Gate entry to be announced. For more information please contact the Auto Hobby Shop on Tinker AFB at 734-5616
I'll get some more info on the times and such but I'm pretty sure it's open to outsiders. I can vouch for a few of you guys.
