Sweet fish! I've been thinking about heading over there recently. The wild fish in there are amazing. Out of all the places I go trying to catch my 20'' wild fish the closest I've come is in there with a 17'' brown. The number of fish in there are amazing also. I think what keeps them alive in there is that most people can't effectivly fish the water where they live.
Sorry to hear about the knee and the big fish. I share your pain with the fish I had a similar experience recently and I can't get the sight of the fish out of my head. I know the only cure is to finally land one.
