I'll never forget descending Lookout Mtn in Golden, CO the 100 or so times I've done it. There are several hairpin turns that lay out down the mountain like ribbons, and they are a blast. Lots of deer though. This is the only video I could find, but this rider's not too fast. 1:30 and especially 5:17 show the best parts of the descent, including views of Golden and the Coors brewery. The rider almost hits two deer. Mute your sound. Trust me.

This is what it looks like (1:30 is the southern part, and 5:17 is the northern part): http://maps.live.com/default.aspx?v=...1000&encType=1
