I hate to drive--I much prefer to take public transportation and walk.  But I couldn't very well ask my guests to take public transportation to the Portola District, especially when one of them has a physical problem that makes it difficult for her even to walk to a bus stop.  So on March 16th,  I was driving like the stereotype of the "little old lady," which I'm now qualified to be.  I drove to Maxine's in Noe Valley, and Maxine drove us from there to  Imperial Gardens and then back to her house, where I took my turn again.  Just as I was approaching the roundabout on Dewey near Clarendon, a police alert flashed on my iPhone,  saying to avoid the area from Claremont to Wawona.  I saw that someone had tweeted that a driver hit and killed two people.  I drove slower still.
