The heavily wooded area about (0:40) is the La Brea Tar Pits & then a park, now occupied by the L.A. County Museum of Art. Guess they murdered all those trees.
Possibly the only business that remains in its original location is the Ralphs (3:24) although the nicely decorated building is long gone, replaced by a store w/ underground parking. The Van de Camp's bakery w/ the spinning windmill a block to the left/west is gone as well. It was an Office Depot but is now a Staples.
Final generalizations: Not one of the gas stations is still there. And you can bet the house & your sweet ass every vacant lot w/ a billboard is no longer vacant.
