I might be mistaken, but I believe it's still against state law in Texas to carry wirecutters in your pocket (from back when cattle rustling was commonplace).
GA used to have a law (maybe still does) that requires each teacher to document the effect of each lesson plan on each child, which would take most of the school day if followed.
In Wisconsin it used to be illegal to purchase margarine. When it was finally legalized, there was a restriction that butter substitutes couldn't be colored yellow by the manufacturer. The margarine you could buy at that time came in a plastic bag and was white but came with a little yellow dye packet that you could pop into the rest of the bag and knead it together to have yellow margarine.
In Moline, Illinois, on Twenty-Third Avenue (one of the major business districts AND the road where the high school is located), they actually have a law against "unnecessary repetitive driving". Translation: they want the kids off the avenue. PROBLEM: that's their high school, and that's where fast food places are, as well as lots of large business parking lots to congregate. Can you imagine trying to enforce this one with anything even approaching fairness?
Todd, out here in sunny California, that one is legally "No Cruising"...and it's local, not state-wide. And at times, our state legislature really resembles Will Rogers' take on Congress.
Supposedly there is still a Blue Law in my homestate of Maine, which requires people to bring a shotgun to church on Sunday, in the event of Native American attacks... Apparently, Maine is full of law breaking church goers.
There is a law I think in a few states that it is Illegal to carry an Ice Cream cone in your back pocket.
It may sound silly, but that use to be a trick horse thieves would pull to lure out horses.
Also, In Texas it is Illegal to shoot a Buffalo from a second story Hotel.
In Indianapolis, IN there is a law against wearing a broach or hat pin with an exposed point of a half inch or more unless it has a guard of some sort.
Indianapolis also has a law that you can't carry an ice pick unless it is part of your job.
Both are carryovers from 1975 when Indianapolis had mafia problems.
Oral sex is illegal in North Carolina. no one follows that law nor does anyone inforce it. but yeah...
Nor could they enforce it. Lawrence v. Texas. Griswold v. Connecticut.
In San Francisco there is a limit to the number of ladies in hoop skirts that can ride the cable car. Further they are not allowed to hang on the out side step.
I know this because they have an annual Dickens Fair and they love to ride and hope for a ticket.
