"A strong body makes the mind strong. As to the species of exercises, I advise the gun. While this gives moderate exercise to the body, it gives boldness, enterprise and independence to the mind. Games played with the ball and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be the constant companion of your walks." Thomas Jefferson

"We were now about to penetrate a country at least two thousand miles in width, on which the foot of civilized man had never trodden ... I could but esteem this moment of my departure as among the most happy of my life."

—Meriwether Lewis
