I don't know much about the Green but had to respond to the time wasted while fishing.
I tried for years to catch steelhead in all the wrong places. Usually to beat the crowds, I fished places that had few steelhead. What it taught me is how to read water really well. I take a lot of pride in that. I feel like I know where steelhead really like to hang and can see it quickly. Hundreds of yards dissected into one little area that is likely best on lots of different types of water from big to small, rocky to sandy with wood.
The interesting thing is that now I spend less time actually fishing on a new river and much more time hiking around trying to find the very best water. Once there, I usally hook some nice fish if conditions are favorable. I kind of prefer it this way. I challenge myself to make fewer casts and use my experience avoiding hope at all costs. Hope is often blind, especially with fishing so always pay attention, compare, inquire, ask, alter, adapt, make mistakes, and get skunked et cetera.
Anybody can go to a destination fishery and hook a bunch of steelhead with just a little guidance. It's a lot harder to actually know your quarry and its habits and have pay off on a regular basis. That is what takes year and years to acquire.
I am a well known hater of the Internet for feeding the me-now generation too much and making them spoiled. It used to take a lot of work to acquire knowledge and it should be that way with some topics because it is the path that counts not the destination.
You will get there someday grass hopper, or not.
