The Blue Angels have been streaking over the city all afternoon. I must admit I feel a thrill when I hear the sound and look up and see a flash. One flew right over me and dipped and turned as it did. I saw one plane, two, four. I really don't know how they fly so close together and so low over the city. For four days they provide entertainment in the Bay area and yet what is the environmental and financial cost?
