Welcome to OCDO!
Don't feel like you have to OC, I don't do much of it myself but I and others can attest to the fact that you will not have any problems OCing in the Springs or surrounding areas.
I wouldn't worry too much about your appearance when you OC. Sure, it is a factor to some but one of the reasons we carry openly is to get the public used to seeing people carrying guns around, no matter what they look like. Presenting yourself as confident (not cocky) and being polite with everyone that you encounter will go a long way.
