There is a track up in Dayton, OH where they do the figure 8 school bus races. My brother's friend entered one year. He made it through the figure 8 race, but didn't finish the school bus demolition derby. His radiator failed him. One guy in the demo derby was playing possum. He turned his bus off about 2 minutes in, then with about 2 minutes left, he fired up the bus and came in second
