I grew up in the house my grandparents built in 1923. It sat on 31st Street and 12th Avenue South in the D7 section of the town of St. Petersburg, Florida, also known as “the Gas Plant,” according to the city’s redline map. I was four months old when they found Emmett Till’s body in Mississippi. A Jet magazine, with the photos of his mangled, tortured body, was always on the living-room coffee table.
