But then it would NOT be off limits because it's a racetrack, but because it was hosting a professional sporting event.
A racetrack is off limits even when no races are taking place. A professional sporting event is only off limits during the event.

Also, I believe the only form of racing that entails pari-mutuel wagering is horses and dogs.

If it were easy -- everybody'd be doing it.

For the purpose of CHL, racetracks are defined as locations that provide pari-mutuel wagering. I believe there is only one in Texas.
Not all "racetracks" are prohibited.
