Ohh trust me they are real amish the stink and all!!! We got a very large Amish population in North Eastern Indiana from around Portland and Berne all the way upto Northwest of Ft Wayne in the Shipshewana area. Lots of "Real Stinky Amish" around here. You can smell them Fuckers 3 aisles away in our Walmart.
Anyone ever seen the documentary "The Devil's Playground"? It's a pretty good watch.
Evidently when they reach their late teens, they are allowed to go off into the "real world" and live as wild as they want, huge parties, drugs, alcohol, sex...all that sort of stuff. It's during this time that they can choose to abandon their families and leave their community or settle down and commit to a Amish type lifestyle for the rest of their lives.
