Weird sentence.
“...as he was driving home along Sunset Boulevard from a job in San Francisco.”
Very odd to say he was driving home along sunset drive from San Francisco almost 400 miles away.
Maybe he’s trying to say he’d driven down from SF and was almost home after the long drive.
Also possible that he was driving back from LAX (or another nearby airport) after flying from SF.
If he was coming home by car, he probably would have taken Rte. 101. Interstate 5 had not been built in 1961, so the only alternatives were Rte. 33 and Rte. 99, which would have taken much longer. He would have followed 101 all the way to Sherman Oaks, where he would have turned south on Sepulveda and then east on Sunset.
Today, I can get to SF (if I ever care to go there) from my North Orange County home in about six hours by road, which is faster than I can get there by plane.
Maybe the hundred or so other folks reading this thread have no clue about the route nor really care.............I know I don't.
Does the route really matter? That's not what the story was about........Sheesh
