If you go to the southeastern part of Missouri, don't even think of wearing this if you're a woman. It will get you locked up and they'll likely throw away the key. That's a slight exaggeration, but it is illegal there and I'll prove it.
I tend to be a history buff. For that reason, I decided I needed to know how and why Missouri ended up with a bootheel. The answers are varied and some are hysterical even blaming Arkansas for the appendage on the bottom of the Show Me State.
