"Carefree Highway" is a song written by Gordon Lightfoot and was second single release from his 1974 album, Sundown. The song peaked at #10 on the Billboard Hot 100 and spent one week at #1 on the Easy Listening chart in October 1974.
The song's name comes from the name of Arizona State Route 74 north of Phoenix: Lightfoot - "I thought it would make a good title for a song. I wrote it down, put it in my suitcase and it stayed there for eight months." The song employs "Carefree Highway" as a metaphor for the state of mind where the singer seeks escape from his ruminations over a long ago failed affair with a woman named Ann. Lightfoot has stated that Ann actually was the name of a woman Lightfoot romanced when he was age 22: "It [was] one of those situations where you meet that one woman who knocks you out and then leaves you standing there and says she's on her way."
This is a regular cache, of which there are far to few of them on the east side of Tucson. Watch for critters and muggles. Have fun!
