What the hell did he chop them down with?
He was fishing or boating, right? I'm not really clear on the details...was he near his vehicle when he capsized? If so, why didn't he drive out? If not, who carries an axe but not a proper survival kit or signally gear? Again, we just don't have the details but if he had the capability to fell four power poles (no mean feat) then he probably had some other options. Oh, well...fools and children, right? Thru divine providence or dumb luck he was rescued and no one else was killed or injured. I guess that's something...
