You've probably seen on the national news lately that the city of Los Angeles is suing local hospitals for dumping indigent and homeless patients on Skid Row.
It was cold the night we were there and while I think that they appreciated the food, they kept asking for blankets. The streets there are more littered than any I've ever seen, save after a big parade or street fair. But we realized pretty quickly that it was because people like us bring food down in containers (in our case styrofoam and brown paper lunch bags) that get left in the street when the food has been eaten. We saw very, very few garbage cans available for trash, even if someone had wanted to use one.
