I searched "homeless" on the LAPL website, and this picture popped up. I find it fascinating and creepy at the same time:
Caption: Two prospective "tenants" look over jalopy jungle at Fourth and Omar Streets just off L.A.'s skid row. Old cars are used as sleeping quarters at night by homeless men, and city health and police authorities have declared the jalopies will be hauled off. Two cars have been burned up in recent weeks by sleepers, police say. Photo dated: March 26, 1954.
