During the cold snap a couple of weeks ago, I found myself at 3 a.m. waiting for a SamTrans bus at the temporary Transbay Terminal in San Francisco, wishing I had dressed warmer. A long-sleeved shirt, sweater, jacket, and scarf were not enough. But relief would come soon. I was heading to San Francisco International Airport to catch an early flight to Miami.
In a reversal of fortunes, the next bus stop at which I found myself was outside the Miami airport. I found myself stripping off layers of clothes as I searched for a shady place to wait in 85-degree weather.
