It's been a whirl-wind week of science fair, little league games, trips to Cupertino, homework and play dates, so Gina and I finally carved time out of our schedules Friday to do a hike & lunch. We found a winner: a looping hike in Tilden Park (between Orinda & Berkeley) that peaked at a ridge with views to three San Francisco bridges on one side, and Mt. Diablo & San Pablo reservoir on the other.
