The topic of Yellowstone Park on another page reminded me of something so I thought I'd post this here as a trivia question:
According to the literature, or at least in the book I read, who was the first fly fisher to specifically use that method of fishing in Yellowstone Park? Also, according to the literature, the purpose of that initial effort was to feed an army cavalry unit which he was able to do with the number of trout caught. Who was this fly fisher?
Answer to follow.
I believe it was General George Armstrong Custer (probably a better fisherman than strategist)
