You want to see something frightening on a lovely afternoon? Check out this amazing interactive map of Ellis Act evictions  in San Francisco put together by Brian Whitty.
It's stunning: Between 1997 and 2013, it seems as if most of the Mission, Noe Valley, North Beach, the Marina, and Potrero Hill was evicted. Hundreds and hundreds of apartments turned into TICs, which now want to convert to condos. Hundreds and hundreds of tenants, who once had rent-controlled apartments, losing their homes -- and given the price of housing, losing their ability to live in San Francisco.
Each little red flag is a human tragedy . Each one represents a transforming city that no longer has room for the middle class, much less poor people. It makes we want to cry. Or throw up. Or something.
