Hardly a day went by during my thru-hike of the Appalachian Trail when the Grateful Dead’s song “Box of Rain” wasn’t playing in my head.
I don’t mean to say I listened to the music every day as it played on my phone. No, it was a soundtrack playing in my head, whether I consciously heard it or not.
The song sometimes played in the background while I was thinking about something else. When those thoughts paused for a moment, I’d discover the music was playing as a second track alongside my thoughts.
