I have been researching a longer project for The Press Democrat for more than a week and still have some work to do. That’s why you haven’t seen many columns by me lately, in case you are wondering. I will cover Steve Kerr’s introductory presser on Tuesday. Ate at three nice places recently, Hansel Bistro on the Guerneville Road, Pane e Vino in San Francisco and the Hayes Street Grill in San Francisco. Mrs. Cohn Zohn says I need to go on a diet.
