I wonder if this stuff we're seeing (I'm in mountain view)
is land based moisture stuff that has developed over
the course of the day and will subside at sunset or
shortly thereafter.
(I think I'm setting up in the backyard. I'd like
to go to hoage, but its a bit of a drive. And I think
the PAS meeting is tonight.. I thought there was
a topic I was interested in.)
