The character played by Darlanne Fluegel, Ruth, has a hilltop house in the film that was located on Viewland Place, on a portion of the street that no longer exists. The film also features scenes filmed at the Vincent Thomas Bridge, the old location of Utro’s Cafe and many other locations in San Pedro and Wilmington.

Most of the buildings on Knoll Hill were demolished about 20 years ago, and today it's home to little league pitches.

I've shot photos of the Vincent Thomas Bridge from there, I thought it looked familiar. Here's one with the Moon rising:
