As it reached Maryland Route 32 it downed a swath of trees on both

ripped off its tin roofing, damaged some roof framing, tore a
large section of fabric from a salt dome, destroyed garage bay
doors, damaged fencing, and continued to snap and uproot large
trees along its path. County employees witnessed the rotating
