I remember being stationed in Prince Rupert about 1966, and I spent all my weekends either fishing or hunting. I had many 3 and 4 day weekends from working over time, and I spent those traveling inland to the Hazelton to Houston area. In those days the Skeena valley highway was still under construction and there were hour long delays going through on the gravel road.
It was late October and I was returning from an unsuccessful moose hunt in the Morice valley, but was stuck in a line-up on my way to Prince Rupert. Although I had been hunting, the guys in the car behind me had been fishing the Kispiox. While we were chatting they showed me what they had in the trunk of their car. They had a limit of 4 steelhead that ranged from 19 to 31 pounds.
That certainly perked up my interest! And, as I was leaving Prince Rupert for Vancouver the following week, I decided to spend 4 or 5 days fishing the Kispiox on my way home. Ha! Ha! Ha! The fickle finger of fate intervened. A few days later a cold front moved in and the temperature dropped to minus 30 in the Kispiox Valley. By the time I got there the river was frozen solid from shore to shore. And, while camping out in the back of my Jeep Wagoneer I almost froze despite my eiderdown sleeping bag. I had to run my Coleman cook stove full blast for 2 hours under the motor of the Jeep just to get it started. Somewhere I have photos of that adventure.
