Sorry, I am young enough that I never went to Cedar Point without a P-O-P admission.
Someone asked why handstamps (not just at Cedar Point) use the word, "DIOV". It might make more sense if you realize the the "D" is flopped left-to-right on the stamp. That way, if you rub your stamp off onto someone else's hand, it won't say "DIOV" anymore, instead it will describe its own condition.....
