Bet you didn’t know our lovely state has a national day, did you? Well, we do, and why shouldn’t we; there is a lot to offer here in the “Show Me State.”. First and foremost, here is a disclaimer: if you look up National Missouri Day, you will get conflicting information; some sites say it is Jan. 4, and other sites say it is the third Wednesday in October. I am using the latter since it was officially ratified by a constitutional convention for Missouri Day to be in October.
