I see that http://www.racingelectronics.com/product-p/2008.htm rents scanners for NHRA, can NHRA attendees bring their own radio scanners into Heartland and listen, like they can Kansas Speedway for NASCAR, and if so where can I find the NHRA frequencies list?
Edit: As good of place to start as any.
