went wheeling yesterday on some class 4 roads. This spot was a washed out section of steep slimey clay about 125' long. I tried to straddle the gully in low low and I made it up about 80 feet and one side would slide in. I tried about 4 times -no go. On the last time, I put it in to 3rd gear low-low and as it fell in I mated it and it made it up.
