Yes, this climb is “fowl” -- I did slow for the turkey crossing however . . .

A lot of scenic pasture and grazing livestock on Sierra Road.

This is the last of three major climb segments of the popular but brutal Devil Mountain Double, hitting you at mile 160 of that ride -- ouch!  There are excellent views of the Silicon Valley to the west as we ascend and there is a nice open-space lookout view area at the top.
