What about the fans going to Paragon and Putnamville? They would affect Haubstadt more than anyone who is going to Mt Vernon. And I'm sure usac or TSS isn't advertising in the greater Mt Vernon IL area. It's my experience there, that as they are running their regular show with the ASCT, most of the fans are there weekly regulars.
I'm sure the Haubstadt show will be like most of the other Sprint Week nights.....standing room only with some awesome racing.
