More than 40 years ago，John Williams gave away all of his belongings and went off to the mountains to live the way people lived 100 years ago.For food he traps wild animals，fishes in the rivers，and plants whatever he can.John lives in a cabin he made by hand，out of trees he chopped down with an ax.Though he has no relatives he knows of，he does have a deer he raised from a fawn.The deer lives in the house in the winter and goes with John when he goes into the forest for food.Nobody lives within fifty miles of his cabin in the mountains and John has not been out of the mountains during the entire forty years.One day last year I hiked in to see how John lives.It was like going back in time.There were no roads，no stores，no noise，no pollution，not even a post office.
