If you are born and raised in L.A. Everything is an abbreviation, there are so many FWYS, roads and canyons we would need a nap after discussing a normal day of driving.It is funny to hear those that are not from here, (try to fit in like a local). We dont give long descriptions of people places or things! Taking the 5- 405-10-2-210-710-15-215 You get the point.Its NOT CALI its SO- CAL, its not THE Pacific coast highway its PCH or Topanga canyon, Laurel canyon, Malibu ETC. Welcome to SO CAL..... the 5th largest economy on planet earth!
