We go through this each year. Ever wonder why the powers to be do not give out these freq. for the fans. NASCAR and most other venues do. They want the fans to bring the scanners and get involved. I think when the have races it should be a given the freqs. would be published along with what ever else is running. I even had a UL official tell me it was because of Sept 11 that they could not give them out! LOL This what I have from last year.
