M_M,
I get what your saying. I agree, nothing does take the place of common sense.
MI doesn't have any true White Water rivers, at least in the Lower Half. I believe there are a few in the Upper Peninsula.
The spot they drowned in even though marked as being a dangerous area and is turbulent compared to the rest of the area, still isn't what inexperienced people would consider White Water. Most flat water paddlers would never think it was so dangerous if not for the signs which are well posted there.
Like you, I also doubt the would be rescuer who died wearing the PFD was aware of what your talking about, or he wouldn't of went in there. From your post, it doesn't appear he was an " experienced" white water paddler but I don't know that for sure? Maybe being a Father he just acted on a parents instinct to protect a child.
I'm was not familiar with those conditions either, but your post changes that. I've made it this far in life by reading signs and giving them the respect they deserve.
Bottom line is the two teens used poor judgment and the brave but mis-guided rescuer payed for their mistake with his life.
I'd like to think that wearing a PFD is a sign that you have good judgment and think before you act.
Your post proves that's only wishful thinking on my part as a PFD is no guarantee of survival in all conditions.
Still, for the vast majority of drowning incidents it's the prudent choice, especially so in the conditions we encounter in the BW/Q.
Now I know when to take it off IF I'm ever caught in such a predicament.
I feel the worst for the poor guy who drowned trying to help. I've been in that position in the Q, watching 3 guys struggle with only 1 wearing a PFD in turbulent/frigid May water.
I knew better than go out there solo but it took all of my common sense to control my natural urge to help someone that needed it. Thankfully in my story, they made it out alive.
Maybe they should mark the inside of PFD's with the following " No substitute for common sense".
Problem is 99% of the people who's lack of common sense/sound judgment got them in trouble would tell you THEY have it and put the blame on someone/thing other than themselves
