Misplaced Apostrophe’s

There's certain subset of our society that consistently misuses the apostrophe. Then there is the subset that is constantly mortified at the frequent misuse of apostrophes.

I’m not solidly in either camp. I know I occasionally, and inadvertently, goof on apostrophe placement and I often catch others doing the same but without becoming apoplectic over it.

Anyway, everyone should enjoy this misuse of an apostrophe on the side of a northern Illinois school bus.
