The participants were the three candidates for Arlington County Board: incumbent Democrat Libby Garvey, Green Party candidate Audrey Clement and Republican Matt Wavro.
Despite the fact that the audience lives north of Route 50, in a neighborhood that has plenty of concerns about traffic, development, aircraft noise and other issues, the main topic of the debate was the Columbia Pike streetcar. The streetcar so dominated the first half of the debate that the moderator had to eventually ask the audience to refrain from asking about it.
