Billboard on the freeway:
ONLY WATER PARK
I can see the choice to ignore all punctuation. It's graphically eye-catching. It makes me want to go there. But on first read, I do a full stop after "Grand Rapids."
The Big Dip. Grand Rapids. Only water park.
If they're punctuation-averse, OK. But I submit that the apostrophe making G.R. possessive must be there... not only because it's correct, but to signal that the next line is a part of the same sentence.
Then, there's this:
I saw this sign days after buying a house sign for "The Sanders'". It made me think of the two minutes spent discussing its punctuation. The lady who was making the sign said there needn't be any, because we're answering the question:
Who lives here?
The Sanders family. The Sanders. Or: The Sanderses.
It's not an answer to a question, it's a statement: this is the Sanders' residence.
Luckily, she was not up for a spirited debate. And, I was the one paying. I'm right, yes? If not, it's already mounted on a house...
