I think the coat industry must love South Dakota. I use no fewer than three coats in a year; four if it rains even once. The shoe industry, too, must have a soft spot for South Dakota. Where else can one man require church shoes, day shoes, hiking boots, and snow boots?
For every shoe a man buys, a woman buys two point five. Look it up.
I bet commerce hates SD because the entire state has less than a million people spread out across the 13th largest state by mass.
