We are fortunate to live near Amish country in Ohio and visit them at least once a year.
The PA area they are not so independant, nearly every amish family sells to Hershey so if anything would ever happen to Hershey they are all out of a customer. There were a lot of activities around there that were not authentic amish, for example buggy rides with an amish driver but hired and paid for trhough the resturaunt/gift shop/motel there.
In Ohio when you want a buggy ride you look on a side street for an older Amish man who can;t work in the fields anymore with a handamde sign saying amish buggy rides by donation and you get more of the real thing.
Its interesting, all the houses will look the same during the day so you have to wait until night then you can spot the amish homes because you can see a lantern hanging in the center of the living room and its usually a LED battery powered one. The one room school had an old laser printer/copier/scanner/fax that was plugged into an inverter connected to a battery under the table charged by a solar panel on the roof, they would turn it on and copy their school papers then turn it off. As high tech as us but still self sufficient.
