San Diego is the only place in CA that I've been. It was Christmas, and the entire country was like single digits or lower except San Diego, which was fine. It was 2017, the year that OSU played USC in Texas, even though both were conference champs and should have played in the Rose Bowl. I had a layover in Texas on the way back to Columbus, where we picked up a bunch of rabid OSU fans that had attended the game. They said it was cold.
