"When we shined our flashlights into the tree, we were surprised to see a bullsnake above us. We watched as the snake cantilevered itself from branch to branch while the robins dive-attacked it, presumably in defense of a nest somewhere in the tree. The drama continued as we turned in, and that night, I decided to forgo my habit of sleeping under the stars. I have observed that the world is divided into two classes of people: those who delight in a physically cozy relationship with snakes and other reptiles and the rest of us whose interest is, at best, intellectual."
