  1. Our power line pole and mail box were snapped off at the ground. And lots of our trees and orchard were pulled out by root balls. Our shingles from house and outer building were tore off, plywood sheeting plus the tin, flew off another building’s roof, and found in our fields. Mini chicken coop was flattened. We live next door, to the badly damaged sugar bush, on P Line, as well. A drive by would still show the road side damage and path the tornado took, and the bush damage was much worse.
