I live in the San Diego area, and a couple weeks ago it was in the High 20's in the morning. Being a transplanted Iowan, I was wishing it had rained during the night so I could get up in the morning, turn on the tube and watch the news reports of massive pileups, and how everything was closed. It quickly warmed up into the 60's. I didn't let a little low 30's, high 20's weather stop me. Still did my 19 mile commute from east county to downtown. I did find out how much my shoes breath as I couldn't feel my toes by the time I got to work. Brings back memories of playing outside as a kid until you were numb and then coming in and warming up only to go back out and freeze again. Heck, I find myself in shorts clear down into the 40's and 50's. Most people in socal bust out the parka's any time it gets below 67.
