Out of the blue, I just got a call from Burnett's casting director for the next ABC "Amazing Race meets EcoChallenge" TV program:

They're looking for teams of 3 with serious adventure credentials and personalities. Get in touch with David (contact info is in the linked PDF) and maybe we'll see you on the TV next year!
darn - you have to be american! looks super fun!
The guy seemed to indicate that strong non-Americans (the right personality/team fit) could apply. I think Canadians might be able to squeeze in particularly well, just a few miles North. You should pursue since you've got nothing to lose!
