Here's an unclear answer to my question....
I decided to leave the gun in the car, rather than risking the walk back...
1. There were no posted signs of any kind. No 30.0x, no 51%. Not even at the alcohol vendor booths.
2. There were walk-through metal detectors at every entrance.
3. After finding our seats I walked over and chatted up two City of FTW officers, one of them a Sgt.
After polite greetings...
Me: I didn't see any signs, but with the metal detectors, I was wondering whether licensed carry is ok here?
Sgt: Are you carrying?
Me:
Me: No, I didn't want to have to walk back to the car, not being sure.
Sgt: I'm pretty sure it's allowed here. If you set off the detector, I should get a call to come vet you. [paraphrasing on that one]
We had a short discussion about publicly owned property rights vs privately managed service providers.... I don't think we agreed that it was ok to post but not against the law to carry past, because it's public property... Just my opinion..
Bottom line: Probably ok to carry here, but, you may be asked to wait to talk with the Po-Po.
Funny sidebar....
When I sat back in my seat, the woman next to me had her phone out and was renewing her LTC online. waiting for the show to start. I leaned over and said "If anything happens, I'm with you"... I don't think she realized I knew what she was doing (hard to miss, since she was holding up her license and typing on her phone surfing the DPS website)... After a few seconds she finally realized and told me "that was funny"..
