Sorry to hear that. FWIW the road promoters aren't happy with turnouts right now either. One of the problems is the TXBRA folks are pretty dismissive of track and are promoters themselves, so they have conflicting interests, and don't do much to help new folks in general (see the clinics and things that other places put on).
I was on the TXBRA board for two years and there's one or two people who control everything. No new ideas, lots of old petty grievances.
The Superdrome is a great facility that the local college really wants to turn into a parking lot. The folks fought that off with the help of the city a few years ago.
