When i was young most of the group I hung out with did open carry, but all of the areas we were in were rural and not built up like today and everybody knew everyone else (different times).
Today I do Open Carry Kinda as I put a shirt over it or a coat but the holster is an Open carry one.
I also do IWB carry as well but that is when I can not put a shirt or jacket over the weapon.
I am so used to this type of carry and at my age I refuse to change as this is the way I trained myself to carry.
So say what you will but I do open carry about 10% of the time but you can guarantee that if you do not see one on me then it is well hidden and I do have a weapon on me.
