My son was doing about 25 down a dirt road that had about 2ft embankments on both sides. He came around a turn and swerved to miss a wash rut and hit a large rock. We bounced up on to the embankment on the right side, then went back across the road and onto the embankment on the left. When we went accross the road we hit hard on the left front wheel. It sounds like a lot of movement for 25 mph but I was with him so I know what the speeds were. I thought we going over at one point. We were only 800 miles from home. I drove it home, towing a trailer.
