There used to be this placed called Cherry Hill in NY and It was a huge wooded area with trails through it for dirt bikes and bicycles. I jumped this Car hood once and man I messed up and came down on my front wheel. Bike was trashed, I was trashed and hit my knee pretty good!!
Never again until I tried a wheelie down this small ramp and landed on my back knocking the wind out of me. Gasp.....That scared me!!
Now I keep both feet planted on the ground where they belong.
