My fishing buddy and I had an experience on the Wynoochie years ago that was similar, but fortunately without a death. We came up on a flipped drift boat and 2 very wet and shaken anglers, the boat was jammed up next to fallen tree and a rip-rap bank. We helped dry-out the guys and went to work on getting the boat free, If not for an old rusty hand saw up in a barn off the river, that boat might still be there. Up-side to this is after about 3 hours of effort the boat popped loose, and about 1/2 of the gear was close by , we found the rest of thier gear downstream as we pushed-off ahead of the boys (the boat was flipped in the 1 technical section of the drift). It was put on mid-stream gravel bars along the way out, as they were the last boat left on the river that day I'm pretty sure they got all the stuff that wasn't on the bottom of the river . I don't post this to blow my own horn, but just to show that 99.5 % of the guys you run into on our rivers would do the same thing without thinking twice. Anything less in my opinon is sub-human.......C/22
