Well I was at the Illinois speed week. I few things I would think about. The tracks are small, but they wind the motors up and hardly let off of them for the whole race. That would have to be a lot of wear on them. All of the nights they had over 40 cars. I would have to think that was a lot of money the teams paid to race 4 nights in a row. The ones that did not make the A main I would think had very high cost each night. Plus they had to be free on weekdays, away from work. Most of the teams are west of Indy, more travel cost to each race. Plus it was not a race ever night. Most time on the road per race days.
