California transplants seem to be all over Colorado, Texas and Arizona. Some parts of these states have become indistinguishable from Southern Californian cities from what I have heard and read. And Virginia and other Southern states are dealing with the same thing with regards to New England transplants.
I work with some California transplants, and they are some of the most petty and vindictive people I’ve had the displeasure of working with. Not to say that all of them are like that, just the ones that I’ve been around.
