Just realize that people are going to stare, point, call the cops, get mad, yell things at you, watch your every move, and feel very uneasy until you leave the area, should you decide to OC. Personally, I don't care what people do or think. I'd rather OC and never need my weapon, than not OC because it makes some Nancy-ass liberal scared.
Criminals will not target you because you OC, that is a horse crap bigoted opinion made by anti-gun sissies and cops who aim to discourage OC'ers. You will have presence that will probably make everyone (including bad guys) think you are a cop or a security guard. Just keep assuring yourself that you're not doing anything wrong and you should be fine. I'd also suggesting thinking of what you're going to say SHOULD you get stopped by an LEO. They are quick on their toes and will capitalize on whatever they can. Know your rights, know the laws, and don't back down. Don't be an *******, but don't be a sissy either.
Personally, its a preference and a lot easier in 100+ degree hear here in Vegas. I can easily obtain my CCW here in Vegas if I wanted to spend the nearly $250, but I just don't see it to be necessary. I carry a Glock 19 and 2 extra mags. MY weapon is always ready to fire and I am always condition yellow ready to move to orange at the drop of a hat.
There is more training you need to go through, but you're on the right track.
PM me if you have any more questions.
