I think the worst thing is that he took his wife and kid along during the steep spot in his learning curve.
Everybody learns and everybody makes dumb mistakes, but he should be out with a few other people who can look out for each other and learn how to read water and maneuver a boat. In that time, he would have learned that river surface flow pushes to the outside corner, that Walmart rafts suck, that Walmart oars suck, that bridge pilings should be given respectful distance, and that GoPros are better left home during the shitshow learning process.
Then he should go out on a sunny day later in the season with his wife and kiddo and show them a good time.
He's guilty of stacking too many unknowns in a little Walmart raft...and then attempting to cash in on the "glory".
Bootie beer time, there, Areyoupreppedtoswim!
