Mack Bates did it in a day back in the 1980's, while he was writing the Three Fingers book. He ran into a couple of old fellows wearing back packs. When he told them how far he had come and how far he was going, one of the men said, "We used to do 40 miles back in the day, but not THAT far". Mack instantly knew who he was talking to. It was non other than Harold Engles, retired former chief ranger for the Darrington district, about whom he was writing.
