About now, high-school seniors everywhere slip into a glorious sort of limbo. Waiting out the final weeks of the school year, they begin rightfully to revel in the shared thrill of moving on. It is no different in south-central Georgia’s Montgomery County, made up of a few small towns set between fields of wire grass and sweet onion. The music is turned up. Homework languishes. The future looms large. But for the 54 students in the class of 2009 at Montgomery County High School, so, too, does the past. On May 1 — a balmy Friday evening — the white students held their senior prom. And the following night — a balmy Saturday — the black students had theirs.

Racially segregated proms have been held in Montgomery County — where about two-thirds of the population is white — almost every year since its schools were integrated in 1971. Such proms are, by many accounts, longstanding traditions in towns across the rural South, though in recent years a number of communities have successfully pushed for change. When the actor Morgan Freeman offered to pay for last year’s first-of-its-kind integrated prom at Charleston High School in Mississippi, his home state, the idea was quickly embraced by students — and rejected by a group of white parents, who held a competing “private” prom. (The effort is the subject of a documentary, “Prom Night in Mississippi,” which will be shown on HBO in July.) The senior proms held by Montgomery County High School students — referred to by many students as “the black-folks prom” and “the white-folks prom” — are organized outside school through student committees with the help of parents. All students are welcome at the black prom, though generally few if any white students show up. The white prom, students say, remains governed by a largely unspoken set of rules about who may come. Black members of the student council say they have asked school administrators about holding a single school-sponsored prom, but that, along with efforts to collaborate with white prom planners, has failed. According to Timothy Wiggs, the outgoing student council president and one of 21 black students graduating this year, “We just never get anywhere with it.” Principal Luke Smith says the school has no plans to sponsor a prom, noting that when it did so in 1995, attendance was poor.

Students of both races say that interracial friendships are common at Montgomery County High School. Black and white students also date one another, though often out of sight of judgmental parents. “Most of the students do want to have a prom together,” says Terra Fountain, a white 18-year-old who graduated from Montgomery County High School last year and is now living with her black boyfriend. “But it’s the white parents who say no. … They’re like, if you’re going with the black people, I’m not going to pay for it.”
