Welcome to OCDO. Congratulations on making the decision to be responsible for your self.
Unless you are doing something to call attention to the fact that you are OCing you should get little attention, as most folks will either a) not notice or b) prresume you are some sort of cop or otherwise "authorized" to OC.
As for the folks who have questioned you about OCing - I hope you have practiced a few stock answers and memorized a few things about the legality and benefits of OCing. Being an ambassador for "the cause" is always good, and helping other folks realize they can do it too never hurts.
I'm guessing you know to stay out of Denver, Boulder and whatever county they are in as those seem to be the trouble spots with laws against OCing without a permit, or OCing at all (can't remember just how hoplophobic they are).
As for carrying SOB, just remember that you need to keep some good friends who will be willing to push your wheelchair if you ever fall hard on your handgun. But if that's the way you like to carry, I'm not going to say you can't or shouldn't.
