Now, to be properly enjoyed, a walking tour should be gone upon alone.... Freedom is of the essence, because you should be able to stop and go on and follow this way or that as the freak takes you.... There should be no cackle of voices at your elbow to jar on the meditative silence of the morning.
Robert Louis StevensonThere comes an end to all things; the most capacious measure is filled at last; and this brief condescension to evil finally destroyed the balance of my soul.
Robert Louis Stevenson
