Personally, I have always thought the promoters cut their own throats when they started piling more and more events into the same area.

Not to mention that Blankenships pissed off a bunch of people with their shady practices.

As far as spectator attendance at the local tracks, it will never be what it was back in the '70's because at that time there were only a handful of national events, so all the big name guys and small guys made their living match racing. Seeing your hero at your local track was the only way a lot of people got to see them other on Wide World of Sports after a month delay.
