In a old video on YouTube of Lee Wulff fishing for salmon in Canada (I believe), he was running a pretty swift river in a canoe. Does this require a lot of skill and practice? Right now, the only watercraft that I own is a 16' Old Town canoe. Is it advisable or not advisable to drift rivers in such a craft? I'm not talking about fishing FROM the canoe, just drifting from spot to spot down the river.
