OK, who has heard of this? Does it not sound like the greatest road trip ever? My initial reaction to this is that it would be amazing fun, but on the other hand, if I actually think about it (or rather, as a friend has just not hesitated to point out, the lovely spoilsport), I am really bad-humored about stuff like camping, and this would probably involve many of the same elements. But then all camping I've done has not been part of the greatest road trip ever. Plus it's for charity, eh?
Would you do it? I think I would. I bet it would be amazing.
