This is a picture of a Hooverville, the migrant shack and tent communities that sprang up during the Great Depression. This one was burned down by the Seattle authorities at least twice.
(Hoovervilles in your neighborhood are very, very bad for real eastate prices.)
It seems that the homeless tent communities aren't gone yet.... We have one in Colorado Springs.
Take note of the online messages about how the Obamaville sign money could've been better spent. "He could've taken the money spent on the sign, and given it to the homeless."
There are times when fighting against the cause of a disease is more important than fighting against the symptoms of a disease.
