I may be an over-thinker, but when you have that many people drinking, stupid shite can happen. I've never gotten in fights or anything close to that, but It's not out of the realm of possibility that some drunkard could try and start something through no fault of my own. If police get involved, I don't want to be in that position.
I'll be attending a daytime parade with small children. I doubt that I would need to pull a gun on anyone at noon, but like the OP said, I don't like the idea of walking down those side streets back to the car with no defense other than a knife and pepper spray.
I can say with certainty though that even if I'm carrying, I'm not pulling the gun over a drunk wanting to fight me.
We all know that it would be worth the charge if we used the concealed gun to save a life. The real worry is getting spotted somehow. Then you'd be facing a felony charge for no good reason.
The "Orleans Parish" will prosecute even though the law says "in a parade" pisses me off to no end. I like living in the country for a reason.
