Patrick,
If they didn't get positive results with this program in the past why do you think they would still be doing it?
I think that's it's kind of funny that you are telling Bruton what he "Should" be doing. I would say that judging by his successes he know's what he is doing. Nobody does more surveying or follow up than the SMI tracks. Also, all his tracks are run as independant businesses. They talk and share ideas and information, but what works in one market certainly doesn't guarantee success in another.
For example, I know of programs that in Las Vegas are huge, but flopped in Bristol. That doesn't mean they did it wrong in Bristol, just that it's a different market that has different marketing needs. I also know that if they decide to try something in Texas all the other tracks look at the program and then decide if it would be worth trying in their market. But the final call in Charlotte is Marcus Smith's, just as in Vegas it is Chris Powell, and Jerry Caldwell in Bristol. Bruton doesn't micro manage. He hires smart people and let's them lead the way.
One more thing, I don't think Charlotte Motor Speedway, would give their contact/mailing list to NHRA anymore than NHRA would give theirs to CMS. I could be wrong, but I doubt it (in this case)
