In 1995 we ran a night enduro on the short course during the Turkey Trot. It was a lot of fun.
Regarding the 3 hour enduro at P.B.I.R., the 30 minutes on Sunday morning are meant to get your car ready for the next 1 1/2 hours, including fueling the cars, check tire pressures, change tires, torque wheels, check fluids, basically everything you can do in 30 minutes to make sure your car is safe to go out on the track. Being an ITA competitor and the Race Director for Florida Region, I hope to see a lot of cars for this event. I'll be out there. If you're a Florida Region member, the races this weekend count for Florida region points for both 2011 & 2012 seasons. All other drivers, this race is the 2011 finale for the TES series and will give you double points towards the TES & FES 2011 Championships. Come out and have a ball!!
