It is SF that is inviting them. If states are paying for the homeless to hop on a bus and go to SF that would be
news to me a good idea for that state. That actually sounds familiar though so I'm gonna hold off on saying it's 100% bull

But all the goodies SF provides are more than enough reason to go.
San Francisco has created this problem. San Jose is getting there too. I drive there every few days and 7th street (for one) is lined with homeless in front of businesses on both sides of the street. Tents, tarps, busted up cars, and a lot of garbage.
The 680 freeway has homeless camps up high on the embankment and all their junk is littered below. They are all over downtown and it is a very big area.
And most of the ones I see appear to be in bad mental shape. I saw a guy run out into the street and try to throw a burning book of matches into the car in front of me through the window.
People are taking dumps and pissing on the side of downtown streets in plain site.
We can't get them off the street, the hospitals were closed decades ago and the street is where many ended up. The old Agnew's hospital is now Sun Micro.
San Jose Police Dept closed the substation on the south side of the city because it couldn't afford it. Years ago. Something is wrong with our priorities, and btw where is all the cash going?
