You are correct but take it the other way around. No one suggested less situational awareness while CCing. I just think it behooves one to have greater situational awareness OCing because of unique situations that are presented while carrying in that manor.
I fail to see how you can have it both ways. If you are suggesting more situational awareness while open carrying than concealed carrying, then you MUST also be suggesting less situational awareness when carrying concealed than if open carrying. Most of us who mix open carry and concealed carry are just as aware whether we are concealing or carrying openly and even when not carrying at all, such as at a school event for our children - at least I am, and most of those I have talked to are as well.
