I have always been intrigued by the Amish. I remember going to Lancaster often as a kid, and I grew up reading fictional books about Amish families. It's fun to teach Caleb a bit about this culture as well.
An Amish family lives right across the creek from Dutch Wonderland (about as non-Amish as you can get!), and they were plowing their fields when we were there.
See the wife leading the horses while the husband gets the hay?
