Midwesterner here. This is correct. Though it's missing anti-abortion ads and the PORN DESTROYS ALL LIVES signs that always follow the Adult Superstore ones.
Also, even for those of us who are out, they sell better sex toys than Spencer's, better lube than Walgreens, and are the only place to buy Wildberry incense for some reason.
And the workers are some of the genuinely nicest people you can meet in the Midwest.
Also the homemade signs on the farmers land. As a kid, I always got a kick out of a sheet of plywood that had been painted with a simple message: "outlaw sodomy."
There's a German style brewery in Columbus, Ohio that sells black shirts with red block lettering that say "Helles Real" and I think it's the best thing ever
Theoretically to check for smuggling and/or theft, I've been told. Come to think of it, if exactly the right weight of merchandise "fell off the back of the truck" to balance the weight of the humans you're trafficking, you'd be safe and make double profits.
Trucks can only be 80,000 pounds max and certain weight ratios per axle (varies by state and conditions). If you're too heavy it could mean shifting the axles, obtaining a special permit, needing an escort, paying a fine, or even being stopped until you can sort it out. It has to do mostly with safety and damage to the roads AFAIK. Also it's where they check all your paperwork and licenses.
The "famous for leaving the Midwest" thing is so real. I lived in a town that billed itself as the hometown of a famous country singer, themed museum and all. Looked it up one time, the dude lived there for like a year when he was three.
Ohio and North Carolina have a license plate beef over the Wright Brothers. They lived and worked in Ohio ("Birthplace of Aviation"), but the first flight was in Kitty Hawk because of the steady winds ("First in Flight").
