This has a more than tangential relationship to AM traffic radio announcers, e.g. KNX and KCBS and north-south announcer mobility. Phrases like "slammer on the San Diego" get into the communal consciousness. It still sounds odd to me when a KCBS announcer reports a "sig-alert". Although apparently now a semi-official designation, it was originally a reference to some radio guy in LA.
