People get used to open carry pretty quickly. Its educational.
Whether one wants to carry open or concealed is a matter of personal preference or sometimes circumstance.
At the end of the day I like both.
Detroit firearms instructor Rick Ector walks around Detroit openly armed every day and has no problems.
Just like my wife. She open carries everywhere.
I usually use a holster that tucks in my pants, still open, but, less obvious.
To each his own.
