I got to meet Mr. Humphreys at Troutfest last year and was very impressed.
I had read in the Fishing Report that he had gone fishing with Walter Babb somewhere in the park. I asked how he had faired. He looked up at me from under his hat with a big smile and said "You know, we went up to a little mountain stream and caught a few....nothing under 20."
Can't speak for his videos but his books are fantastic.
