There used to be a 10 foot mound of dirt to block a trail at the end of this road that was like a Tee intersection. I would ride down the road as fast as I could, check for cars at the last second fly across the intersection and hit this pile of dirt as fast as I could.
One time after a big rain I did the jump but someone had driven a 4 X 4 down the trail and dug a 3 foot deep tire tread on the other side of the jump. when I landed my front tire went in the hole my back tire hit the top of the rut and I flipped over the bars and stuck my head in the mud right up to my shoulders. I just had time to pull my head out and blow the mud out of my nose before I passed out. When I came to my front tire was a pretzel but I was uninjured.
