My thanks to everyone who posted messages of sympathy and support. It's good to have friends who care about you.
Oh, and I did try the alternative route around downtown Palo Alto, and while it worked, having to make two unprotected left turns (on to and off of Alma) during heavy traffic times is almost as bad as having to swim through the heavy tide of University Avenue traffic. And, wouldn't you know it, I got a phone call, and this was one of the few times I'd forgotten to put on my headset, so by the time I was able to get pulled over to legally answer it, it had gone to voice mail. No really big deal, but it's one of those "it figures" things.
