We have always disliked the terms "sustainable" and "responsible". Even though they are accurate and self-expanatory, they suggest a schoolmarm striking you on the wrist and telling you to behave. Visting a place and knowing that you have not damaged it envionmentally and culturally, and perhap even leaving something positive behind, is as much a joy as a duty. Our old friend the late Robbie Collins, who worked all over the world to promote conservation of culture and the environment through travel, liked to use the term Good Travel. We do too.
