Light Up the Lakefront is back at Rio in Gaithersburg this Saturday, December 6, bringing one of the area’s most popular holiday traditions to the waterfront. HOT 99.5’s Intern John, and The MoCoShow’s own “Mr. MoCo,” Alex Tsironis, will once again take the stage to host the event from 4:00pm to 7:00pm. The free celebration promises an evening packed with lights, music, entertainment, and a fireworks finale over the lake (video of last year’s event below).
