Finished with the four Highway Patrols. In the third, I got an address and the name of the side street but could find no such street in the Valley, which is the only place the main address would be - interesting. In the fourth episode, an amazing shot that I knew instantly was Las Palmas in Hollywood - the church at the block south of Hollywood is unmistakable. This shot was looking south from Yucca - the two street signs clearly visible. I'd bet the apartment building is still there.
