Good people who have a higher than average incidence of incest and sexual assault? Good people who run puppy mills, breed dogs into the ground and then let them go roam free to get hit by cars when they're done breeding them? Good people who destroy their road horses' legs and dump them at new holland for a slaughter broker the second they can't manage the miles as easily? Good people who ignore fishing and hunting regulations, and regulations about not burning toxic trash?

Not really. It's very, very rare. Sometimes the "English" will get a former plow horse as a pasture ornament/steady eddy type for kids/visitors to trail ride. And sometimes regular/non Amish farriers don't want to work with the big drafts who aren't as good about keeping their hooves up for farrier work so in those cases I suppose someone might use an Amish farrier with stocks. And I suppose some people who like driving horses might get harnesses from the Amish harness makers, but very few non-amish drive horses.

Gnerally the non-Amish in southern chester county are looking for a much, much higher quality of care than the amish provide.
