This question isn't exactly on-topic but is pretty close. The Texas town I live in has a town park with a sign at the entrance listing all the "Not Allowed" items or activities inside the park. Examples -- No Alcoholic Beverages, No Littering, No Fireworks, etc., but smack dab in the middle of this list they have "No Firearms." Can towns prohibit CHL holders from carrying in town parks?

A second question just came to mind that is more off topic but I'll ask it while I'm here. A lot of lakes in my area are Army Corps Of Engineers lakes. I'm assuming that the shorelines are under their jurisdiction (this could be a bad assumption). If they are, are Texas CHL's valid, say while fishing?

Thanks in advance.
