Presidents and First Ladies Trivia

[L Verge]

I'm warning you now that I am on a trivia roll. As part of one of our conference bus tours, my tour coordinator at the museum put together a tough history quiz to keep folks occupied on the two-hour trip back. Therefore, I am going to spread the wealth of trivial information to y'all. If you happened to be on that tour, please wait awhile before submitting your answer.
