Pity the poor californian

Last night, riding the roadbike at about 7 pm, several hours after dark here in post DST November, it was too cold to ride in a t-shirt. Even when I was warmed up. At least on the easy fast bits. It has to be 55 or lower to wear a jacket when I'm running. Looks like 60-65 is about it for biking. Hopefully my running jacket can do double duty.
