I grew up in the upper Hollywood Riviera, Redondo beach. That zip is 90277; you can clearly see where they cut the street lights, as they do in the 90277 Redondo zip code, and continues into pv. The only time it turns Torrance is the hill off Riviera elementary, arena / colusa. Driving away from the school, the driver is sitting in Torrance, while the passenger is in Redondo beach. Rocketship is Torrance.
RAT does not stand for anything aside from your interpretation. Redondo and Torrance, Redondo at Torrance, Redondo after Torrance, etc.
It’s not PV until it crosses that line all the way before you hit Malaga, after the flags. Follow the trail behind arboles. That’s where PV starts.
