Speaking of the Philadelphia area, twin brothers just west of the city have been arrested for exploding devices. While fortunately no one was hurt, they did do some damage to several structures, including an “Amish phone shed”.
…the brothers then exploded a pipe bomb in an Amish phone shed on Dec. 30. An Amish phone shed or phone shanty is an enclosed building containing a phone used jointly by multiple Amish families, who do not permit phones in their homes. The shed was badly damaged.
I actually took a college course that studied (in part) the Amish, but I was not aware of this rather absurd practice.
