Perhaps this will become the ultimate in reality tv. Think of the book rights. Think of the sponsors. Heck who even cares what happens to the participants, the ratings will go sky high.
I think a special event caravan is a great idea. I think going where there is likihood of incidents is not. I can't see justifying that risk.
I'm with the other posters that would also like a challenging exciting trip in Byam style but think wiser destinations should be explored.
