If you are for a merry jaunt, I'll try for once who can foot it farthest: there are hedges in Summer, and barns in Winter to be found: I with my knapsack, and you with your bottle at your back: we'll leave honour to madmen, and riches to knaves, and travel 'till we come to the ridge of the world. Dryden's Spanish Fryar.
