Gentle on My Mind is one of my favorite songs.

''Through cupped hands, round a tin can
I pretend to hold you to my breast and find
That you're waiting on the backroads, by the rivers of my memory
Ever smiling, ever gentle on my mind.''

It is a song about hopping freight trains, and thinking about the girl you left behind. I have hopped a lot of freight trains. Love this song.
I have been there and done that a dozen times, sitting by a campfire near the railroad tracks, drinking a up of coffee and thinking of my girlfriend back home.
