You are correct, that is a violation of Tx law.
That means lots of bending, jumping, stretching, picking up kids, etc... and that would cause me to print. I spend quite a bit of time a public parks.
Dewhurst doesn't give a damn about my personal safety, or the safety of my grandchildren. He only wants to make his GOP-E country club buddies happy. And open carry makes them uncomfortable.
My grandkids would feel better if I could carry in the park like I carry at home, though. They have said so.
