I once got a free downhill ride.

Drove Angeles Crest Highway and stopped at Dawson Saddle where I chained my bike to a tree (a bit off the road and out of sight). I then drove on to Vincent Gap. From there I hiked to the top of Mount Baden Powell and then instead of hiking down and wrecking havoc on my knees I went on to Dawson Saddle.

The downhill did not last all that long. It was fun.
