I've posted this
video before, gives a good idea of what it's like going fast down a decent. This is the same decent I did 56 on. Also (and not at the same time) on this road I've had a car pull out of a driveway in front of me, and another time my brake cable snapped near the bottom. Fun stuff.
Edit: Anyone who races anywhere with any kind of hills just has to accept fast descents.
