I have seen articles indicating some states have been known to stick people on a bus and ship them to California.

I run several homeless sites and routinely read r/homeless. A common question is "Where can I go with better weather than where I am currently?"

I spent several years homeless. I was evicted from my apartment in Georgia and walked and accepted rides to cross the country to get back to California. So I basically camped my way across the country.

I'm quite confident I know whereof I speak on this specific detail.

Though just to be clear, I am not suggesting we ship all our homeless there, though it absolutely is true that some portion of the homeless population in California traveled there from elsewhere in some fashion.
