Auto Club 400 sold out

All 68,000 grandstand seats "have been sold" for today's NASCAR Sprint Cup Series Auto Club 400 in "another boost for a once-struggling" Auto Club Speedway. Of course the track used to have 91,200 seats but they removed 23,000 to avoid the embarrassment of empty seats. They also went from two Sprint Cup races a year to one, so count how few seats they sell now compared to what they used to.
