Over the years I hiked the 98 mile long West Highland Way in Scotland. The first time in the conventional way, South to North and greetings were pretty rare as almost everyone was heading the the same direction. The next time I hiked it was North to South and it got to be a real PITA to keep saying "good morning" about a hundred times a day. Recently hiking on the 840 km Spanish Pyrenees trail GR11 I daily met so few people on the trail that there was a real thirst for conversation which seemed to be shared by everyone I met. Problem was with the various languages of all the other hikers.
