Who could expect such behavior from Amishes who live in small communities and have no TV, telephones and all that modern stuff. You think they can't enjoy the life and make up awesome party?
There's a period of time in Amishes' life when they can leave their community for a while and taste the world. Few young Amishes snatched at a chance and decided to have a buggy party.
However it resulted in a crash of a buggy carrying four Amishes with the patrol car. Here are the consequences - the buggy was flipped, one of the Amishes injured.
