Then ... Larsen has been assigned to tail suspect Camerero, beginning at a small gym alongside the bay.
... and Now, the gym, still there, belongs to the South End Rowing Club and the Dolphin Swimming and Boating Club at 500 and 502 Jefferson Street at Aquatic Park (map). On the right, above, the schooner moored at the Hyde Street pier is the Wapama; it has since been dismantled and in its place, below, we now see the square-rigged sailing ship Balclutha. On the left, there's a small jetty...
... here's a view of the gym in a recent photo looking back from that jetty.
Then ... next up, an energetic game of handball.
... and Now, the court, in the same building, continues to keep club members on their toes.
Then ... Camerero moves on to a hairdressers with a window view that identifies this location... that's Fredericksen's venerable Cow Hollow hardware store across the street.
... and Now, the same view from inside the store that currently occupies this site. On the left it has since been expanded into the store next door.
The store is currently the Simply Chic boutique at 3038 Fillmore (map) but back then it was a men's hairstylist called Forum II.
Fredericksen's has been serving the Cow Hollow neighborhood at 3029 Fillmore since 1896. In this recent photo the part of the store visible through the hair stylists' window in the Then image above is outlined in yellow.
Then ... The surveillance continues in a parking garage as the suspect walks to his car.
... and Now, this was filmed on level A of the underground garage of One Embarcadero Center in the Financial District.
Then ... But when Camerero exits the garage, this isn't One Embarcadero Center...
... and Now, instead, it's the Clay Street exit of the Golden Gateway Garage across the street from One Embarcadero Center (map), viewed from a pedestrian bridge spanning the road.
Then ... Jake follows him to a narrow back street where he pulls up to the rear door of a club.
... and Now, CitySleuth has yet to find this location. Does any reader out there recognize it?
Then ... Another day but still tailing. Larsen tries his best to look inconspicuous when Camerero walks right by him after exiting the narrow alley flanked by the pair of concrete bollards. Note the vertical sign - 'Poster Alley'.
... and Now, this is Union Street in Cow Hollow - Larsen was sitting at the steps of 1960 Union Street (map) in the center of the seven-block stretch that back then was a much-touted tourist shopping favorite. Poster Alley ran alongside the Artisans poster and framing store at 1964 Union, there since the early 1950s. Customers could view posters and prints hanging in the alley and buy them in the store.
Artisans is still in business but recently moved to the Sunset district. In a sign of transition the photo below taken in January 2016 pictures the empty store up for lease. The bollards are still there on either side of the garage door that now blocks access to the old Poster Alley.
