I hear ya. Was raised and lived many years in the San Gabriel Valley.
Saw a chart the other day that the SGV is now 46% Hispanic, 26% Asian and 22% white. How times have changed.
I went to San Gabriel High, and lived in the house that Sammy Pierce built Indian Motorcycles in, then he rolled them across the street in to the store. My Dad bought it in 1970 from him, they were friends
