Just don't drive it to an Irish pub or Celtic festival. A British Para reenacting group in Austin, TX made the mistake of dropping into an Irish pub for a pint after a WWII reenactment and had to do some very quick explaining to stop the patrons from beating them to a pulp.
Oh dear........classic example of re-enactors who actually know very little about what they are representing, despite many being ultimate nerds about widgets and grommets.
Just the thing for putting round holes in square heads.
