Saw 2 streakers back at the old Irwindale in early 70's. One just ran down the track for a bit & got into a van. (What if the guys in the van kept the door closed?? heh heh) Other one was a nekkid guy on a drag bike. I kid you not. Announcer was going nuts. As far as bad oil downs, pick one from the 1960's - 70's. There were 2 guys in the bed of a pick up. They would each have 50 lb bags of oil dry powder. Pour it on the track to cover the oil down. Then come back down the track, each man with a push broom. Repeat until the oil was (mostly) cleaned up. Whoever got that lane was screwed. Oh, and you had plenty of time to go to concession stand, the restroom, take a nap, etc. Been thru my share of those.
War story. Once at the old Irwindale, Larry Sutton was the starter. Just before the T/F final, oil down just off the starting line in right lane. Got it cleaned up. Leland Kolb was in the bad lane, James Warren in the left. Larry told Leland to make another burn out thru the grease sweep. Worked, cuz the final was a great race. Warren won with a 5.99 and Leland ran 6.12, but it was side by side. I heard Warren in the winers circle, said that he saw Leland "all the way down". I remember Leland was really on his game that day, put a hole shot on everyone. That was an old WCS race, Div 7, back when the Pro cars ran with the sportsmen. Was like a mini nat'l event.
