Idiots playing with fire

Earlier this evening, there was a BOOM significantly louder than the pop pop pop of fireworks. Sounds like they blew something up, I jokingly remarked to myself. Looked out my bedroom window to see A LOT of black smoke. Dashed to the living room window (not blocked by crappy trailer next door)--flames were clearly visible just over the wall of our park, less than 50 yards away. I swiftly went and packed the essentials--meds, devices and their cords, "good" jewelry...(not necessarily in that order), though they had it contained by the time I was assembled. I'm leaving it packed overnight, because these yahoos are still at it. Yikes.
