Summary: Change has swept over San Francisco like a hurricane, but there are bits and pieces of an older city everywhere. You just have to look, sometimes in odd corners of the city.On Evans Avenue in the Bayview is the world headquarters of L. Ph. Bolander & Sons, which sells flags and flagpoles, a niche business with deep roots in the city. Their products are found atop hotels and stores, and in front of police stations and post offices.
