This doesn't sound like it meets the "professional sporting" much less collegiate, high school, or interscholastic sporting event. It is not 51% and the statute says racetrack and racetrack is defined. So I do not think it is unclear, but I could be mistaken.

There is one caveat though- if the location you are at is a 51% location - just no alcohol sales at your event, it is still prohibited. 51% locations are always in effect even if at the time they are not selling alcohol (which is stupid).

That said, why would you want them to post compliant signage? LTC holders statistically are the most law abiding group of people in Texas. Why would you want to make it a GFZ and more dangerous? As long as you are not consuming alcohol I would think you would want to carry since from your description they apparently do not provide adequate security.

Just my .02 worth.
