Ca. Bay Area winters are brutal!

Grew up in Minnesota so I got used to the cold . That was a humid -20 !
My son and I used to go skiing in Utah for a week each year .
1 day we were standing in line at the lift waiting for it to open when I look at the digital temp display and it read -10 . No way did it seem like below zero ! Probably around 10% humidity (if that ) . That was at about 10,000 ft of elevation ….
Makes a difference .
