This is actually a re-creation of a planned dismount that went horribly wrong. When I first started riding my 36er after a 50 year break from unicycles I was not comfortable riding across the bridge. So I had planned to ride up to the start of the bridge and dismount. I hit a bump at the start of the bridge and took a header clean off the bridge. It was about 12 ft down to the ground below but the ground was soft and I sustained no real injuries. It was my most exciting dismount to date.
