I bent the crossbar on my handlebars with my chin while running a new course...showin' out in front of the chicks. Came to a gully hidden right behind a short rise, never could tell there was a 15 ft deep 15 ft wide gully until I was ten ft away....nose dived to the rise on the other side...forks stayed compressed till I bought a front end to replace the bent one. I learned right then to ride a new course over at slow speed. That was 36 years ago. I sure miss it.
