Piling On

This (faded) destination sign on California 128 near its interchange with US 101 at Cloverdale has apparently been remodeled over the years: note the button reflectors that are used only for Boonville as a supplemental destination on the sign. You can tell that they're button reflectors because they stand out from the rest of the sign, casting a little shadow in the mid-morning sun.
This photo was taken in August 2009.
