I live in south dakota, people in hick towns actually ride horses to the bar, that is why this law was set into motion. Can not remember the stats for DUI arrests in the state but it is in the top 3, the midwest being the home of the most drunks in the country.. But yeah in the bigger cities in the state you do not see drunks on horses or people on horses in general just big ass pick up trucks. I rather see the drunks ridding horses and bikes then driving big trucks.
