Grow up. Have a kid. Move to Del Ray. Jennifer Walker rules the Alexandria neighborhood; you’ll need to give her a call. The Griffin, Ga., native reinforces her unofficial mayor–of–Del Ray role by driving her electric car along Mount Vernon Avenue and during local events such as the Halloween parade, Art on the Avenue, and Cinema Del Ray, which she sponsors. “I got so into it I went and bought my own popcorn machine,” says Walker. Oh yeah, and she also sells real estate. On any given day, you’re just as likely to see a blue McEnearney sign with Walker’s name on it as you are a pair of married intellectual-property lawyers pushing twins in a caramel-colored Phil and Teds. Walker’s been selling Del Ray since 2000, when Nancy Dunning, a fellow real-estate agent, took her under her wing. In 2003, Dunning was killed in her home on West Mount Ida Avenue. Walker had big shoes to fill: Dunning “really did everything here,” Walker says. “I decided I was just gonna be myself. You look at real-estate agents and they have big hair and big fur coats and big cars, and I just didn’t fit that profile.” Del Ray’s rough edges are mostly gone—“There was a lot of drug use, some prostitution,” says Walker of the neighborhood at the turn of the century, noting that the Evening Star Cafe is in the former location of a biker bar. Even harder to imagine, the neighborhood wasn’t a haven for fecund Type A’s. “I tell everyone who moves here, I’m like, ‘Don’t drink the water,’” says Walker. “They’re like, ‘It’s too late. We’re already pregnant.’”
