I think a couple of factors contributed to the low car count.
1) Ohio Speedweek still going on, you'd have likely picked up a couple of drivers that raced Sharon on Sunday.
2) The massive rain delay that Knoxville had definitely cost us Brian Brown and likely Ian Madsen from coming as it was a 5-6 hr drive from Iowa and they got done around 3am.
I think you'd have had 27-31 cars if not for those 2 things.
Was a pretty good race anyway, Schatz 23rd to 2nd.
