The heat broke today: it only got up to 90 degrees in Palo Alto before the cool air started to move in from the Pacific, and now it’s already down to 69 degrees. It’s supposed to go down into the fifties tonight in San Mateo. That’s the good news.

The bad news is that school has started again, and family vacations have ended. All summer long, the traffic on the freeways was merely miserable; now it’s back to being completely insane.
