A lot of Kensington, too.
I worked at two offices in the area ( one block from K&A and Hunting Park) in 1999. Lots of boarded up homes and businesses then. It must be worse now, and the blight has probably moved further up Frankford Ave.
The blight has spread up Frankford throughout the NE part of the city. You can blame the spread of section 8 (and drugs) but alot of the problem is just abandonment not seen in NYC since the 1970s.
