My experience is that you can carry almost anywhere---the bad guys do---if you keep it well under wraps.
I know you can't carry in a hospital--but--I have. I am not going to walk a half a mile from a free parking too the hospital, at night, in Houston, in the Medical Center, unarmed, just because they are afraid I will open up on the staff of St. Lukes.
Don't ask, don't tell.
