Almost 25 years ago I worked at a wilderness lodge in southeastern Alaska. Part of my job was to turn off the generator at night. Afterward I would sit on the porch steps of the lodge, luxuriating in the non-manmade noises around me. The trees rustled, the Taku river waters splashed, somewhere an owl called and was answered by another from a different direction, sometimes the lone wolf howled from the deep forest, and I watched as a satellite traveled steadily around the sky and disappeared.
