We actually never made it to the site. There was a big thunderstorm about an hour before we left the main road to this site. When we turned on to the road leading to this place we got stuck on the road. It seems that the road is clay and when it gets wet it becomes very difficult to travel on. Although the road is flat and level our Ram Van with all-terrain tires got stuck. After 3 hours of placing sticks and other things under our tires we managed to get out. Spent the night in a nice free park in Pierre.
