I had the opportunity to visit a few Amish farms in central Missouri last fall. We enjoyed being able to buy farm fresh meat (some still twitching!), eggs, and such, and from what I saw and what I've heard from others' experiences, the Amish are honest, hardy, and hardworking. Their buggies shared the road with their neighbors' cars, and I was surprised to see obviously non-Amish homes in the area.
Also, I've seen Amish craftsmanship of barns and lofts and things on occasion, and have been impressed, and clients I've talked to had nothing but good to say about their carpentry work.
