Now are the West coast people from tougher stock or are they not getting
those muggy mid/high 30s nights? (I think that's around 95F).

In Pacific NW waters, we seldom see temperatures in the mid 90's, even in the
middle of the day. A "hot" day around here
is a temperature in the 80's. In 2003, we set a record for consecutive hot
days; this is the first summer we have seen 50 or more consecutive days where
the temperature rose above 70 degrees.

I always run my diesel heater, (for at least a few minutes first thing on a
chilly morning), several times in July and August.

Opening a few cabin doors and windows
brings in cool, sweet, ocean air on our rare muggy days, extremely preferable
to running a gen set big enough to power 4-6
heat pumps. :-)

And no, we're not tougher stock. Ask anybody who comes here in the summer from
the central or eastern part of the country. When the temperature hits 85-90
degrees, most locals are bitching about the "heat"! It's always cooler down by
or on the water.

Conversely, it seldom freezes hereabouts.
We often go an entire winter with *no* snow at all, but typically we'll get 2-3
dustings of a few inches. A major snowfall here is 18-24". Our rugged natives
cannot deal with snow. At all. Schools and some government offices close when
snow falls and sticks. Our normally horrific traffic becomes totally
unworkable, since nobody gets any practice driving in the stuff and there's an
accident every several blocks.
(This has become worse since people started buying SUV's. They charge down icy
side streets at 35-40 mph, the dumbcluck drivers completely assured by TV
commercials etc that they don't need to modify their normal driving techniques
because they have "four wheel drive"!)
