What do you guys wear on the river? I am working on planning a trip on the birch in september. I bought a book about rivers in AK and it recommends knee high rubber boots. Everyone down here in OR claims that is a very bad idea. The rest of the clothes recommended seems to be about the same but the footwear is the point of contention. So recommendations with an explenation of why you wear what you do would be appreciated. And if you want to through in any other recommendations feel free.
