The bowling alley was built by the old parking lot. The lakes were paved over for the new parking lot.
A 'Wild Mouse' was built about the center of the picture. The 'Rockets' ride had burned down and was converted to a large food stand. The upright thing at the bottom was a pylon-shaped "Willow Grove Park" sign at the back entrance. The 'Scenic' coaster is still there, just hard to see behind trees.
