Then ... After planting the tree Maude drives Harold back over the Dumbarton Bridge along Highway 84. When she passes the same cop who she humiliated earlier he can't believe his luck and immediately gives chase.
... and Now, the same spot alongside a pylon on this now unused stretch of the highway (map) is seen here from the elevated causeway that replaced it.
Then ... he catches up and has to pound on the car to catch her attention. At the top of the hill is the toll plaza seen in their first encounter, viewed from the opposite direction.
... and Now, as explained in the preceding post the toll plaza has been moved to a rerouted section of Highway 84. Today this part of the original highway, Marshlands Road, is the access road to the Don Edwards San Francisco Bay National Wildlife Refuge.
Then ... Eventually Maude deigns to pull over, not far from the toll booth.
... and Now, that same roadside location (map).
Then ... The cop orders them out of the car but when the unsuspecting clod gets in to check it out, Maude beckons Harold to his motorbike, he hops on behind her and with a roar they zoom off past the toll booths.
... and Now, the same view today.
The final ignominy for the hapless cop? He takes a pot shot at them but his gun misfires.
