"As I drove across the New Mexico Painted Desert, I found myself singing softly, "This land is your land, this land is my land...," the Woody Guthrie alternative anthem that was enjoying a revived popularity. It made me think, no, this is not your land. I was driving through the Navajo Nation as a guest, not an owner. I wondered how the Navajos or other Indians would feel about that song."
January 1, 1970
