I would say the problem in the zone now is that many people go there because that is where the fish are (that is what they are told).
They don't fish fly tackle at home.
A)They have been told or read that you have to get on the bottom to catch these fish so they put on too much weight.
This makes them
1) hang bottom, getting in the way of people that do know how to fly fish
2)They have been told how light these fish bite and you must set on anything.
3)A+1+2 =dragging bottom and therefore setting the hook all the time
4) then there are the long time well practiced lifters and liners there to get an ego boost from the 1 2 3 guys that don't get that they are POS aszholes cheating good people out of the chance to catch these fish fairly
This weekend it was worse because the fish were so hammered by the crowd every second of the day light hours.
Even the most aggressive were just trying to find a place to hide lessening the fairly hooked fish number.
