My son moved out of SF proper for a smaller nothern california city last month.
He made a reservation for a U-Haul truck. They wanted $500 or just $80 if he would bring the truck back to SF. When moving day arrived, he went to his local U-Haul office that he had scheduled to be the pickup location. They said sorry, you have to pick your truck up in some little burg that was a 3 hour drive from SF. What? He called U-Haul main office. They said his reservation guaranteed him a truck but not a pickup location. He said then cancel my reservation.
He called and I said he should never have used U-Haul, the trucks I’ve rented from them were crappy anyway, and that I always use Penske now. So he called Penske and they got him a truck – in SF – within a couple of hours. All they had was a 26 footer so he took it. Scared the crap out of him driving that in SF! Can’t recall what he ended up paying for that but I think it was similar deal to U-Haul.
So yes there is an exodus from SF. The moving truck situation is telling.
