Having been walking and hiking for exercise since 1990 I have these observations. When I go alone I always have a walkman . I have over 75 cassetes recorded thru the years. Rock music, jazz, soundtracks... a nice mix .Just need that music to go. I notice others have a walkman, ipod or headphones. Some walk their dog. When I am with someone or a group I enjoy the conversation. A feeling I don't like is out on the trail and the batteries go dead! Oh no! Tried a cd player, but too many skips.
