Problem with CHL's and carrying. You are REQUIRED to be more aware as to where you can and cannot carry. Also you need to look for the signs. It is up to the proprietor to decide if he/she wants to allow licensed handguns or not.
I had a friend who got told by a cop that because she took the course she is more responsible than before. She cannot even "display" the weapon to discourage someone, aka open up a jacket to reveal the handle etc.
I am not against having one, just be careful out there
