We waded the lower Big Hole in the area where it braids near Twin Bridges, so we did not try walking into the upper area where you apparently were, Fishboy. We floated the section around Wise River and got out a few times to wade, but they were probably unreachable by walking in, although I don't know that for sure. The main stream was, like you said, not wadeable enough to cross, but then all the fish we caught were within a couple of feet of the bank for the most part.
