When I'm long distance hiking, for no reason I can understand, an old song will start working my mind. When I was on the AT "Erie Canal" an old folk song by Ed Ames or Bearl Ives started working on my brain and I would humm it all day when alone. I hadn't heard it for 30 years but I couldn't get it out of my mind. In real bad weather "The City of New Orleans" by Arlo Guthrie seemed to keep my spirits up. This is not the music I listen to at home or in my car but on the trail alone these two songs just stay with me. I am just wondering if any of my fellow hikers experience this strange mind trip. (I carry a Sony but never listen to it while hiking because I love to listen to the woods)
