The only difficult parts were the high winds in the Tracy area that blew me around a bit, heavy fog above Colfax, and the descent from Donner Summit, where it was wet but not snowy, but where I wasn't sure about ice. The solution in both cases was to slow down and take it easy, which I did. I made my usual fuel stop at Lodi Jct. and visited my sister in Sacramento for 45 minutes. As I said, there was no snow on the highway, just a lot of rain. East of the summit, the rain lifted, and it wasn't even especially cold. Lisa had been working on building up the wood fire in the house and had things tolerably warm by the time I got home.
I'm grateful I was allowed to leave a day early. Tomorrow, however, is a regular work day, so I need to get unpacked and get some rest from the drive. Fortunately, my commute is much shorter and the shower is in my own house, so I don't need to get up at 5:15 AM.
