We were in this area (but not this town) this summer. The thing that cracked me up was a horse drawn hay baler with a gasoline engine on it to power the baler.
We were told that scooters were OK and bicycles were not because you can travel faster on a bicycle than you can on a horse.
Also, it was OK for them to ride in a motor vehicle as long as they paid for the ride.
I expected the Amish to be reclusive and shy, but they were employed in many businesses we visited and were extremely friendly and polite, though a bit reserved.
It's hard to imagine such a horrific event befalling these private people.
I've seen quite a few of those. I gather that as long as the propulsion is not from engines it is OK. They also have very bizzare-looking threshers with gasoline engines. They also seem to have no problem with pesticides - I've seen them with horse-drawn sprayers.
But the manure spreaders are still fair-sized tankers pulled by horses. Whenever I saw a field up ahead painted dark brown, I knew I was in for an olfactory delight when I got there.
