If people must know...
3 people fishing, but I spent a lot of time taking video and photos.
Actually in two days for two people, so that's 36 / 4 = 9. Only 9 fish a day per person.
We spent a total of approximately 11 hours fishing between the 2 days. So, we were averaging a steelhead nearly every 15-20 minutes of time on the water. Don't forget to incorporate approximately 5 km of hiking into each day as well. It was epic, "only" 12 steelhead each for the trip - I'll take that. 12 fish is normally at least 3 full days of the water for me - not less than 11 hours of casual fishing.
Just to keep the thread on track...
