It turns out that the temperature falls to near-freezing at 5,500 feet (1,675 meters) in Southern California in mid-May, a fact that it never occurred to me to check when I packed summer clothes for a visit to the UCLA conference center in said mountains last week. After all, I have lived in California for half of my life. What was there to check?
My host for the occasion was Jesse Thorn, co-host of the blog Put This On among other accomplishments, and a man appropriately dressed for the temperature in a corduroy suit. I on the other hand am only marginally warm enough at mid-day in lightweight gabardine trousers and a linen shirt jacket.
Always check the weather in advance. As if you needed me to tell you that.
