Earnhardt, Jr. was going to give some of the proceeds from the race to a charity. He chose Charlotte Humane Society as one of the possible charities, and each charity was assigned 2 numbers, each representing a position. For example, the 2 CHS numbers were #1 and #39. If he came in either 1st or 39th place, the CHS got the money. If he came in 2nd position, the charity holding #2 won the money.
Cheers!
