It is legal and it might be in your car but not in mine. The state law not withstanding, I allow for common sense, apparently absent in the S.D. legislature. Same reason I don't allow open alchoholic containers, legal in Missouri, in my car. It leads poor decisions, that effect everyone in the car or potentially even out of the car. I don't really see the need for or thrill of road hunting anyway. But that subject has been worn out here. I bet S.D. has a seatbelt law, what a joke, you have to wear a seat belt but you can carry a loaded gun in your lap, with your safety off and finger on the trigger! Which do you suppose is more dangerous, and to whom?
