I called up there today to find out what they are trying to raise money for. The IMRC has records on all forms of racing, from Formula 1 down to Saturday night circle track racing. They do one big fund raiser like this a year.
They told me that the car has a little over 1,200 miles on it, and that the guy donating it bought it new. And as of yesterday (08/19) they had sold 1,000 of the 2,308 tickets.
Brian, does the owner's name show up in any of the records you have?
