Reminds me of the famous Irish road sign in Donegal
"If you going to Dublin I wouldn't start from here if I were you"
I didn't see that one but perhaps it wasn't there in '66.
@FrayedBear I think the story might be apocryphal, my late father in law swore it was there, but was never able to produce a picture of it.
Yeah, now I know exactly where NOT to go.
Useful advice, yes?
