It is my understanding that Open Carry is *not* illegal in Wisconsin. The AG has apparently submitted an opinion that Open Carry is not against the law and persons open-carrying should not be harassed by law enforcement.
Wisconsin does not have a carry permit, and it is required that one not carry while driving a car. How does that apply to a motorcycle? Can I open-carry while on my motorcycle? There isn't a trunk on my bike, save a couple saddle bags.
