"The first U.S. state to . . . have Elvis" is an interesting choice of words. I can't argue that the clue isn't technically correct as written, however.
Just my $.02 - I like the idea for this quiz, but don't love the execution. Why give a hint on one question (and only one question) when there are several that are probably more obscure? Also didn't like the phrasing on the Elvis question or the Super Bowl question...
Only got the nuclear reactor question because of Simpson lore... and George H W inferred that the simpsons weren't useful to American families hahahaha
I'm assuming Quizmaster was thinking about the start of the civil war in 1861. But South Carolina definitely seceded on December 20, 1860.
