It is a sad thing for sure. I've flipped canoes & have gotten into them full.Bailed out & floated again.I've also had to get on top of it after it was rolled over. 55 degrees is cold ,but I think the dad was not a canoeist.He'd have saved their lives. They did have their pdf's on. It just goes to show us that we need to be aware of how to get out of trouble once we get into trouble.

Even eminent chartered accountants are known, in their capacity as fishermen, blissfully to ignore differences between seven and ten inches, half a pound and two pounds, three fish and a dozen fish. ~ William Sherwood Fox, Silken Lines and Silver Hooks, 1954
