Past Sat. did my first ever dh on barrowed Cove shocker with dual crown and protective eq....gnarls fun. Kids said they took me on fairly difficult intermediate trails, since I had never done it...I would not know any better and just have to go for it or puss out (they were hoping I'd die and they get some insurance $). Well shit my pantz...steeper than any stairs I've walked down, with just inches to clear the bars, rock ruts, trees and a few little jumps...a couple places there was no trail and the trails were half as wide as in Argo's clip. Apparently I killed it; only went over the handle bars once and hugged a tree mid-air while the bike kept going. Wish I'd done a gopro of it. Damm kids talked me in to trying more shit.
As Agro notes...its a total commitment thing...just drop and go...and don't lock up the wheels. My shoulders, forearms and hands are feeling it...and was surprised how out of breath I was for rolling down hill. The cross country stuff looks like a piece of cake compared to the dh stuff.
