Watch Julia Martin, 87, Slay the Electric Slide

Saturday's Porchfest coincided with another big community event -- the 10th anniversary of the Julia Martin House. The 55-unit building offers something scarce in JP: Affordable housing for the elderly. Julia Martin, the community activist the complex is named for, was guest of honor at Saturday's celebration. She's in purple in the short video below. The Julia Martin House is one of the many properties whose rents or sale prices are kept affordable by the JP Neighborhood Development Corp.
