People will bring up The Madison, Beaverhead, Smiths River, Henry's Fork, etc... If you mention The Green to them then they suddenly remember it but when just asking people don't seem to bring it up. Which is great. The best day fishing I have ever had was getting into a mayfly hatch 200 yards up stream from little hole standing in the same spot and catching fish after fish for a couple of hours. It was absolutely insane. The hatch and rise was so massive you were guessing if it was your fly that was being hit.
