Having driven Hacienda Blvd (including the non-boulevarded part, very confusing) I can imagine that used to be sparsely populated. :’)
Ah, yes. Hacienda Blvd., Highway 39, all the way to Huntington Beach, baby!
My Cousin from Jersey came to visit us with her mother one summer, and she would not believe me when I told her I went to Manhattan Beach several times a week to surf and sun. I actually had to drive her over there and show her the city sign before she would admit that yes, there is a Manhattan Beach in California, LOL!
