By 09:30 high fog moving in from the West and limiting magnitude worsening
rapidly.  On drive home generalized thin fog at ground level, but a very dense
layer of fog about 100 feet up very noticeable near the many cell phone towers
and over the limestone mine W of where I observe and over Ames (SW), Gilbert
(NW)and Nevada (SE).
