We were riding along and saw a windmill That was actually working so we rode over to it to take a look. Door was open, and it had postcard and info on the bottom floor so we went in and started climbing. The owner was on the third floor and he showed us the inner workings. He grinds flour in the mill and sells it locally. He showed us how he stops the rotation of the wings and engages the wooden gears. It was a lucky thing to find along the way.
