Misspelled words
Believe us, there are a lot of words that we can not spell correctly without the help of a computer. Even while writing this we have our moments where we forget how to spell even the most basic of words. It happens, we are all only human after all and we make mistakes.
But we would have never guessed that we were not alone in our spelling shortcomings, it would seem that each state makes some mistakes. We do not even want to attempt to spell these words without looking at the map, we do not blame any of these people for not getting them on the first try.
