Well, they probably DID have one at some point.
That sign USED to be more centrally located out front, not so much off to the side as it is now. After about the 10th time it had been backed into by a patron who had had a bit too much, they kinda re-located it...
Actually, the last time it got backed over, it was leaned up against the side wall of the joint for at least a month before they finally put it up in it's new spot.
So, any actual hitching rail probably got the same treatment withOUT the relocation.
