I worked with John at Crater Lake NP in the early 80's and he was a great friend, wonderful father and husband to Diane.  John introduced me to fly fishing, putting a fly rod in my hand for the first time, a pursuit I continue to this day.  Though John would be just as happy with a ball of cheese bait, a beer and a lounge chair.  John was party to the infamous 90wt oil fish fry cookout with Roger Rudolph and Mark Forbes, which I will leave them to tell the story. It did not end well, at least for me. John was fine national park ranger and superintendent and a good man. He will be missed.
