At Gas City, in 2008 they let anyone into the pits for two hours befor the program started if you bought a 50/50 ticket for a dollar. I think this was 4pm to 6pm and worked on a honor system. When hot laps started you had be out of the pits. This would let fans talk to their favort driver and get a racing shirt. They have a new prometer this yr, so that policy could change.
