No, things don't happen everywhere like they happen in the cultural bubble of Los Angeles. There wasn't a KNAC or KROC in every town in the 70's, 80's or even 90's. There isn't a Hollywood sign, Hollywood Walk of Fame,or In 'n Out Burger in every town either. I've lived in 7 states and 11 some towns/cities, including LA, and don't remember ever hearing ALS outside of Get The Led Out. It's a deep cut.
