It’s the stale stench of liquor and human waste that hits you first. Then it's visual -- row after row of dirty tarp tents crammed together on the sidewalk next to piles rotting trash and broken appliances. There are half-dressed, drugged-out shells of people wandering aimlessly in the middle of the street. Some curse at cars. Others just stare. There are fights, prostitution and rodent burrows. This is Los Angeles and it's a disaster.
