Growing 'tent cities' blamed on foreclosure crisis

A few tents cropped up hard by the railroad tracks, pitched by men left with nowhere to go once the emergency winter shelter closed for the summer.

Within weeks, more than 150 people were living in tents big and small, barely a foot apart in a patch of dirt slated to be a parking lot for a campus of shelters Reno is building for its homeless population. Like many other cities, Reno has found itself with a "tent city" -- an encampment of people who had nowhere else to go.
