Yeah, usually I watch the show with focused attention, but last night, it was just more or less playing in the background as I puttered upon the computer.
You mention the possibly disguised industry standard life jackets. I wonder if the duct tape "rope" was really disguising a certified rock climbing rope...for safety and liability contracts. Which leads one to wonder how many of those shots were really Adam and Jamie. I will admit at least one or two of those shots with Adam thrown from his canoe and rolling through the rapids really looked like Adam. If it were a stunt double, the production certainly matched the performers better than some other shows.
And the show always loses a few points from me when Kari is not present.
