In 1972 I was privileged to take Pete on a whitewater raft trip for several days on the Snake River in Hells Canyon on the Idaho/Oregon border. We were still fighting to preserve the canyon and river from a major dam proposal. Pete was supporting us and, while there, wrote a song about Hells Canyon. I'm saddened by his death. He was one of the great humanitarians of this century and last. And a great conservationist as well. Rest well, Pete.
