Your readers might be interested to know that in Lakewood, Ohio, houses were considered blighted if they lacked attached two-car garages, three bedrooms, or two full bathrooms; even the Mayor's house was blighted under this definition (More information on the Lakewood case is available here: http://www.ij.org/private_property/lakewood/backgrounder.html). And if you or your readers would like to see what "blight" looks like, you can check out pictures of these charming houses from Norwood, Ohio, all declared "blighted": http://www.ij.org/private_property/norwood/norwood_homes.html
As a New York City resident, turns out that most of my friends and I have lived in blight conditions for years. But then we suspected as much. Fortunately, Paul's organization, Institute for Justice, was able to help prevent the condemnation in both of these cases.
