Thomas, re: fly fishermen snagging, I have unfortunately heard and seen too much of it. It does happen. You'll see it in groups that fish for chums and sockeye. Despite great evidence to the contrary, there is a certain group of non-sportsmen who use fly gear who persist in believing that sockeyes and chums will not strike a fly. These folks think it is therefore justified to line the fish and try to snag them in the mouth. Some of them are pretty good at it.

You see most of the sockeye lining in Alaska in the roadside streams. I have seen some of the chum lining here in washington. Which is sad, because it is easy to catch doggies fairly.
