It depends, if there is a heavy marine layer and an on shore breeze,
the Peak will often be fogged out first. If however the air in the area
of the Peak or Coe is relatively steady but humid when dew point is
reached both locations will have fog.
I have been at the Peak a number of times when moist air coming
off the ocean will form clouds as it goes over the Peak. At these times
it isn't unusual that a mile or two down the road from the Park the sky
will be clear.

ps Mike, what "exciting projects" is Mojo referring to in his article
about Fremont Peak published in the SJAA newsletter?
