Out on a river in a little aluminium boat, ill equipped.

I watched the first quarter, then shut it off.

It seems to me he was so busy filming his next episode that he forgot the most basic things. He didn't even do an inventory of his pockets -- forgot he had a whistle that would have brought rescuers to him (five boats went by).

Yeah

The other blunder, is telling his wife where he was going, only to change is mind later on and not inform her.

At least he survived and suffered a bit to learn a lesson.
