Well, I'm here in LA and temps have been mostly bearable. We've only had a
week of near 100 temps since summer, but many days btw 88-92. Fortunately,
my AC doesn't need to be on until the later afternoon most days and we shut
it off after sundown unless it's still in the high 80-90s. But we do use
heat in the winter, not as much like eastern climes but still need it. The
difference is that most of the homes here have terrible insulation unless
they've been retrofitted. All these crackerbox houses built in the years
following after WWII are horrible compared to other parts of the country,
and the crappy ones in the worst neighborhoods are still going for $500k...!
Don't get me started... ;-)
