As others have said, it is posted. However, I believe it is owned by the city, so non-sporting, non-school events would be OK regardless of posting.

That said, about 2 years ago I tried to find definite, concrete proof of who owned the ATT Center (I wanted to print this out in advance of going there for a concert). I wasn't able to find anything concrete about who owned it. The address doesn't show up in the county appraisal district, which matches with it being city/county owned. (After all, if a private business was that large, they'd want the property tax revenue right ? )

I still hope to find this info eventually, but am at a dead end now.
