Many years ago, I had to explain to a new co-worker who came out to SoCal from NJ. a little bit of our history. He "didn't understand why everything (meaning the names of cities and other things) is in Spanish". He was astounded to hear that Spanish was the overwhelmingly dominant language until at least the early 1900's and is now on a par with English, on its way to dominance again. Here in our region of the US, it is truly bi-lingual, and that's a good thing. Just like Canada.
When I was the news director at KFBK, I had a group of young reporters who I overheard one day discussing why they thought California had all these Spanish names and how "Sacramento" wasn't one of them.
They were astonished to learn that the capital city is named after a river that the explorers said was as sweet as the Sacrament of the Lord. In Spanish.
