The Yahoo ads for tents and campgrounds under the pictures add just the right touch of irony.
You're right - the ads are funny. A large number of bums used to "winter" in Sacramento along the railroad tracks near the Loaves and Fishes charity that provides food to vagrants. The situation got to the point that the local business owners (without permit) took chainsaws to the brush and stretched concertina wire along the property line. There was some ranting and threats made but I don't remember anyone getting charged. The tent city in the photos appears to be across the river in West Sacramento.
