I was telling my cousin about this thread and he told me a story about a race he attended where the main was a 60mins. One of the driver's did not go to the bathroom before the main. Mine you the driver was 3 third in the race. The driver decided to go on himself to save his position. The pitmen below were dodging yellow rain drops......He finished 2nd in the race. My cousin said that there was a 30 minute delay to rinse the driver stand and pit area down.
