i have never been to badlands but my buddies and I go to haspin because its only about 40-45 min from home, we always have fun there, we usually camp for a night and there is a lot of people that drink and drive down there and it makes it a little more dangerous but if people are responsible and dont do that its awesome, we either ride the trails on quads and dirtbikes or we go down the trails on smaller trucks, some trails you cant take trucks down because they are to small or have tight turns so i reccommend not going through many of them unless you're with somebody that knows it pretty well, we've seen many people get stuck on the trails that nobody else could get in to pull them out
