Be sure and remind him that the fence lines run N-S and E-W in Iowa.
Great help in navigation.

Don't they run like that everywhere? When I got my training in Ohio, I
was never taught to use the furrow/fence lines in navigation, and I
never even noticed that they could be useful for such. Once I started
instructing in California, I happened to notice they can be really
helpful in navigating, and I now can't imagine trying to navigate
without them.
