Not sure about Texas..In nearby NM, the one's I'm familiar with are:
Federal buildings, like a Post Office, Court House, etc..
Schools & University Grounds.
Establishments that sell liquor by the drink....I've heard that some establishments might post a sign that CC is prohibited in their business...To be honest, I've never seen one....
I'm sure there are others, maybe another poster can name some more...
