Aha! Helifishing is when you get there by helicopter, not fishing out the side of a hovering craft. When I saw the title I was wondering how you'd get the fish to ignore the noise. I bet you can reach some pretty sweet fishing spots that way...no road, not boat to row home. Makes me smile just to think about it.
I love the contrast between the timeless beauty of the woods and river with the modernistic helicopter.
