As long as I've lived in southern California I've never heard the Sea of Cortez called the Gulf of California. I'm looking at a map on my wall and it is definitely labeled as Sea of Cortez...where did this other name coming from?
Born and raised in Southern California and always heard it called Gulf of California -- never referred to as Sea of Cortez, even though I know it has that name as well.
Maybe time for an update soon? The ludicrously-coiffured faeces-witted freak who is soon to become president of the Neo-American Empire has his own ideas about reality and nomenclature that might clash with JetPunk…
