my tailbone won't be talkin to me for a few days
my friend said i did good for my first time doing anything like that(snowboarding, skiing, etc.) i did a few end-over-end flips accompanied by pops in my neck and back; sliding foreward on my face for about 5 meters, twisting my ankle while trying to figure out how i'm supposed to move with one foot in the binding and the other pushing... not to mention i have crappy balance
i think i'll go once more just to make sure i don't like it, then i'll just stick with mountain biking and rock-wall climbing
