There really is nothing that could make a book and nature lover happier than a Sunday afternoon during which you acquire a used, 4-volume set called The American Seasons by Edwin Way Teale, and then watch your son wade in the shallow stream next to the Reader’s Quarry shop and catch small crayfish in the sun-dappled water. From Journey Into Summer, volume 3 from the set:

To the lost man, to the pioneer penetrating new country, to the naturalist who wishes to see the wild land at its wildest, the advice is always the same–follow a stream. The river is the original forest highway. It is nature’s own Wilderness Road.

I am thinking our crayfish may have been the Allegheny variety.
