I love the part they say " where like minded people come together "
I know back many years ago ( fred, norm & connie ) when they would sell out. Obviously the price was " reasonable ".
Once the price hit the $30.00 mark it was rare there was a sellout unless the water was so low it was the only game in town.
As for it being crowded at a sellout.. That all depended on how one chose to fish. The wall, joss, glide, spring, meadow and any named hole was full of people.
I always liked fishing moving ( not literly ) fish in between those areas as the rested in shallow water behind an eddy.
Those areas , at least then were not crowded because people didn't realize how to fish them. They would try the same old drift method , get hung up and leave for deeper water. The swing with very little , if any weight other the the fly was the key to success.
Now , at least in my last trip down there people have figured a lot out , not everyone actually fishes for them ( there are snaggers abound there too ) but many have learned that you can catch them instead of just hooking em'
