factoid (2) - an assumption or speculation that is reported and repeated so often that it becomes accepted as fact.
Absolutely 100% made up. So, if that's the most interesting thing about each state, and it's fictional, imagine how mind numbingly boring the corn states must be
(I'm joking ofc, Ohio has a few redeeming qualities. The southeastern portion is particularly beautiful, Idaho has some staggering vistas, and Iowa… I mean, 75% of their name is vowels I guess)
