 Pete Perringer with Montgomery County Fire and Rescue also says discarded fireworks smoldered and erupted in the Wheaton area, causing damage to the outside of a home. And early Thursday morning, multiple packages of fireworks were seized after two vehicles crashed on I-270 in Rockville. For anyone thinking of setting off fireworks this weekend.
