I was talking to a guy who lives near the Amish. A few years ago some Amish families got together in a barn for their Sunday church services. Their services tend to last 4 or 5 hours. The service was in the upper part of the barn, and most of them tied their horses in the lower part of the barn. During the services, things got noisy downstairs and several times they had to go down to stop a couple horses from fighting. Things would quiet down for awhile and then start up again. Suddenly the whole upper floor dropped part way down and all the church people fell to the center of the building. It was total chaos.
I turns out one of the horses was tied to the center beam of the barn, and pulled the beam down.
He said no person or horses were badly hurt, but that was the last time they tied their horses down there.
