They believe everything they think they see in media.
For some reason, people who don’t live in our state, appear to think that it is all sun, sand, beaches and palm trees. Only true in a tiny fraction of California, and even then, we have to import the palm trees.
I recently attended a conference in Louisiana and was asked if it was always 76 degrees and how many movie stars I saw on the street on a daily basis!!!
They don’t seem to understand how large and varied the state is and how congested the roads are.
The cost of living is ridiculously high, especially housing, so there are a lot of homeless people on our “sunny” streets.
California’s agriculture is massive, so a large portion of the state is made up of farms. These areas are somewhat affordable for housing, but most transfers in don’t want to live in a farm community. People from the Midwest will be trading from wheat and corn to citrus and organic farm products.
