I also longboard, and I liked the part in your essay when you talked about adrenaline because that's the best feeling when you longboard. Also, I can relate when you talked about speed wobbles, those are the worst.
I know how it feels when you fall off. I fell of my friends longboard, after I broke mine, and he laughed at me but it was worth it. I proved to him that I would go down the hill we call 'Death Hill'.
