Fun quiz, though "Wore a Panama Hat" seems a not very specific clue. There are plenty of pictures of FDR wearing one, other presidents like Coolidge had worn them as well, yet only Truman worked.
Thanks for making this and introducing a new element to the game play, but, even though forewarned, there were too many repeats. I'd prefer a series of quizzes with unique answers than one quiz with a randomized answer bank.
