The Oregon Department of Transportation paid $1 million to place boulders where neighbors had complained about homeless people camping. In San Francisco, CNN reports, the city removed a few dozen boulders paid for and placed by neighbors. The city said people were pushing them into the street, creating a safety issue.

The Portland boulders created some controversy but remain. In California, the boulders are being held until neighbors and the city can talk about solutions, according to CNN. What do you think about this tactic to reduce sleeping on neighborhood sidewalks and open areas?
