We didn't find any farmer's markets, and one grossly over priced fabric store with nary an Amish woman is sight.
Here we have a flea market where the Amish sell their crafts, five fabric stores in a ten mile radius, the original Lehman's and the restaurants are not only reasonably priced, they are clean, the food is outstanding and your waitress will likely be an Amish teen who will graciously answer questions.
Don't get me started on the furniture shops!
You have to be a local to know about the farmer's markets. They hold them in different places on different days, and they are out in the middle of nowhere. But if you really want a Pennsylvania Dutch experience, that's the place to go.
When I first moved here, I was a business consultant. I was hired to do some planning for a local meat company. They had a picture on the wall of a guy loading meat into the back of a wagon. The owner told me it was his great-great grandfather. I replied that his company must have been in business a long time. He said that his family has sold at the farmer's markets continually since the 1750's, more than 100 years before they even had photographs.
That taught me a lot about the Pennsylvania mindset. They have deep, traditional roots and they are very slow to change.
