Yes, I remember the "Parkside" episode very well. At the time I thought it unfortunate that they made the area look so scruffy. Having been to the theater a couple of times, I had nice memories of the place. Malden and Douglas were great together in the series, and it was fun to actually travel around SF to see where the settings were. One episode used my Alma Mater Lowell (the old red brick building on Hayes St.) as the setting. The two detectives spent a lot of time driving up and down the Embarcadero, south of the bridge. Wide streets, many big, unused warehouse buildings meant less traffic, more freedom to film than in busier parts of the city.
