Congrats to @wolverinealum and your son! Wish him the best!
@Nhatrang , I think more specifically, you will lose your kids to Northern California if they go to Berkeley. We live in sunny SoCal, not LA, and even though S1 got a job offer here, even with the obscenely high rent up there, he still chose the Bay Area, because, he said, all his friends, all his connections are there, he will have more opportunities.
