Technological Exceptions
While technology isn’t allowed in Amish communities, there are a few exceptions. For example, the Kalona community has more relaxed rules within reason. Tractors can be used in the fields, but you can’t take them on the road to drive.
No Wedding Rings
The Amish have a strict dress code, so wedding rings aren’t worn. They’re seen as a way to draw unnecessary attention to the person’s body, which could induce pride. Therefore, the bonnet color symbolizes that a woman is taken instead of the ring.
