Our municipal fireworks show has been cancelled, which somehow also cancelled the fog that so often accompanies what evolves into a 'colorful fog show.' There IS a marine layer, but it is diffuse.
The call-and-response of M-80 to car alarms has continued all week, and reached a peak earlier this evening.
(This is a view looking north/northwest from the highest point in the Ingleside. The range and peak in the lower right distance is Mount Tamalpais. It isn't clear enough to see the white observatory on the ridge there.)
