I encountered a number of Amish communities on my x-USA trip last summer.
In Spencer, Ohio, a young, single Amish guy gave me a ride in his buggy.
I had tried to engage two guys in German at the store.
All I said in German was that I sure couldn't understand their German and they laughed.
They speak a Plattdeutsch from the 18th century.
In Rebersburg, Penna, non-Amish neighbors drove Amish families to the store.
Each Amish community decides its own level of use or non-use of technology.
Whether something is seen as prideful or disruptive to the community is the main factor.
I helped a family load a van with a week's supply of groceries -
And in the process learned how they chose to accommodate technology.
Amish people are people first. Too often they are besieged by tourists who see them as "quaint".
Please avoid taking pictures - even at a distance - it is not what they want.
A frequent misuse is to photograph Amish people from behind. Why?
Here are are the relevant pages of my posted journal for Indiana and Ohio:

It doesn't aim for Amish communities - but there are many.
Millersburg in Holmes County, Ohio is an Amish center - plus the area has good bike trails.
And the historic Lincoln Highway traverses both states - the old road has light traffic.
