In an effort to keep local officials thinking about the proposed Purple Line, local transit activist group Action Committee for Transit is organizing a flash mob in downtown Silver Spring Thursday evening.

The group plans to meet at Colesville Road and Wayne Avenue at 5 p.m. Dressed in purple to show their support for the Purple Line — the light rail planned to run from Bethesda east to New Carrollton — the group will be doing a three-minute dance while holding signs, said ACT President Tina Slater.

The flash mob, which 64-year-old Slater said will be her first, will coincide with one in Baltimore organized by the activist group Red Line Now aimed at drawing attention to Baltimore's pending Red Line.

ACT officials said they felt there was a need to draw attention to the Purple Line partly because of a decision by County Executive Ike Leggett to delay the construction of a south entrance to the Bethesda Metro station. Although a council committee voted Monday to restore the project funds in the county's capital budget, the decision still needs the approval of the full council.

The entrance is a necessary step toward the completion of the Purple Line because it would connect the Metro station to the Purple Line station planned to be built next door, Slater explained, and delaying its construction could delay the Purple Line as a whole. 

"We don't want any dawdling," she said. “I will go out and make a fool out of myself for a good cause."
