This doesn't even pass the SMELL test - duct tape

I sort of doubt the guy got a really good look. This was after dark I belive. Maybe it was metal strapping, which might look like duct tape under poor lighting. But duct tape would probably work. It's not like it has to hold for very long.

It could very well be duct tape, especially if the walls have slatted boards. Two raps and bingo! But thats not the point, to conclude that this is a hoax based on whether or not duct tape was seen or is feasible is not too smart.
