These cars are headed to the highest speed kink on the track, where someplanner(s) decided to place a grandstand for handicapped spectators, 'protected'by a fence that might stop a kite at 180mph, but never a 1500 lbs projectile. Inthe low speed exit area of the hairpin, nobody was allowed near the fence. Go figger...
