I've met some very happy, very spunky Amish horses and some very 'dead to the world' ones.
Just like us 'regular people' not every Amish person is a great trainer, and some may even treat there horses in an old-world kind of way. All depends. I personally like the Amish in my area, the horses all look quite happy and their always polite and friendly. Even when I come with my silly questions like "Excuse me sir, but do you know where I could possibly buy the stuff that goes under the buggy? The metal doohickeys?"
"The running gear?"
