We are two days into a six-day white water rafting adventure on Idaho's Middle Fork of the Salmon, often referred to as The River of No Return, and as usual, I am powerless to stop my son from adding another heart-pounding feat to his stash of adventures.This time my husband has joined the fray, and the two of them are about to catapult through Class IV rapids in a flimsy-looking rubber thing called a "Daring Duckie." Smiling like a couple of "Jackass" pranksters, they lurch onto the river.
