I’m as anti-militarist as any good Berkeley resident should be, but I’m sitting in my office in the Presidio (an army base for three different nations over more than 200 years) with my heart leaping. Why? The Blue Angels are practicing for their shows in San Francisco over the weekend and it so happens that my building is right below dozens of fly-overs by the screaming jets, tearing through the skies. An incredible sight.
