On the day we left, Dad was ready to till in the cover crop in the garden. The kids had already been treated to an exhibition of the tractor, with the mower attached, mowing two-foot-high crimson clover down. We took the opportunity to see the next step of the process as well, the tilling. Since it involved an impressively loud machine, it was naturally a good show. My favorite part was watching them trail after Dad like little ducklings.
