Allan and Linda visit the park together, but first she meets him at his office. As they leave they pass a red and blue poster (behind him), advertising the British Exhibition at the Masonic Hall on California Street.
CitySleuth has not yet found this location but is including it here in the hope of a reader recognizing it and contacting him.
Then … Linda is conflicted by their mutual attraction. She’s feeling down so at the park Allan tries to cheer her up the only way he knows how - with wisecracks.
… and Now, This was filmed in Golden Gate Park at the Music Concourse in front of the bandshell (map). The steps in the background lead up to the De Young Museum.
The bandshell, named the Spreckels Temple Of Music in recognition of the gift by sugar magnate Claus Spreckels, has hosted many notable performers over the decades ranging from Luciano Pavarotti to the Grateful Dead. Built in 1899, it survived significant damage in the 1906 and 1989 earthquakes and is stoically awaiting the next big one.
This recent view from the De Young Museum tower looks across the Music Concourse to the California Academy Of Sciences and the transmission tower atop Mount Sutro. Note the array of heavily-pollarded trees covering the concourse, seen closer up above. The bandshell is on the right.
