Amish country in Pennsylvania was a lot more commercialized than we imagined. It seems that the Amish have given up the idea of just ignoring the tourists who want to gawk at them, and have decided to take some carefully controlled commercial advantage of the interest.
There are a number of Amish in the buggy ride business. We rode Aaron and Jessica's. (Those Amish websites — they're crazy about Flash.) You get about half an hour tour through Amish countryside, and even up to a house, where they have some crafts you can buy.
