The Scoring Pylon (showing numbers 43, 86 and 95), along with the one at the Motor Speedway of the South, is taken from the Indianapolis Motor Speedway.
Despite Darrell mentioning that the final race had an attendance of 200,000 cars, there were really only 100,000 cars in production terms plus an additional 1,500 in the aisles and infields. This is still larger than the 60,000 cars at Motor Speedway and 700 in its infields. Also, 13,000 cars are entering the stadium to find seats.
