I LOVE flying down hills, and I think it's because I had a big hill I used to fly down as a kid on my wee 1 speed.

I get out of the saddle, stretch my legs so that my rear end is out over the back of the saddle, my arms are long, my head is kind of between my shoulders, and I look where I want the bike to go.

It also helps to say, "WEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!"
