Per Ralph Mowery:
I
have seldom seen anyone open carry that is not some kind of law. There
are a few , but not many that do.

Ask anyone that is in the know and they say open carry is about the
dumbist thing to do.

That would seem to support my suspicion that there is a
greater-than-average chance that the carrier is, perhaps, running a
quart low.
