I saw one guy on a motorcycle wearing 5.11 pants and then noticed his barrel peeking out from under his jacket.
Another guy in a vest at a gas station, same thing wearing on the waistband with too short of a cover garment.
Both cases, I looked at them closely because of the way they were dressed.
I live in an open carry state, and I think there is something to be said about crummy concealment being at least better than open carry. That is as long as you don't intend on ignoring any signs.
