Looking for a unique way to see the Buffalo herds near Custer State Park (map)? You might look into a Jeep Tour. Here are pics showing a Wagoneer and a later model jeep built to hold a small group. Here are some links that might be helpful. It’s not clear to me if there is only one tour operator or multiple ones.
