Calaveras covered with loose gravel
One of my favorite roads - I went to ride it today, and it was covered from about a mile south of Sunol Regional Park with about a half inch of loose gravel. I didn't bother to ride it past there (the sign said the fresh gravel went on for 7 miles), but turned around and went to work. I think if it really went on for 7 miles the entire road is probably covered with fresh gravel all the way to the bottom of the wall.
I hate it when they do that! (although I do appreciate well maintained roads). I got my rebuilt bike back late yesterday, so this was my first ride on it. At least that worked.
