In upscale areas of CA, most houses are 2nd homes.  In the area where I have my 2nd home in Napa, I volunteer on the mutual water company board as treasurer.  Out of 35 houses we serve, there are only 8 full time residents.  This is typical because CA taxed out people who have incomes and can afford to live there but don't want to pay obscene taxes so that Newsom can ruin some more stuff, make more kids insane and trans and import more illegals.  We actually had large fires and lost 5 houses on the street, 3 have been rebuilt.  Fire evacuation in CA, despite mismanagement, actually functions.  Evacuations are ordered well before the fire reaches their neighborhood, so you won't see a lot of footage of people actually fleeing the fire.
