The only reason we don’t open carry like that anymore is we don’t want our stuff stolen. In days past you could leave a rifle in the rack and windows down while you ate or shopped. Not anymore. I hide what I am carrying.
We can return to those days. It will take the same kind of resolution and faith that we had 200 years ago.
