First off... that vid clip is one of the most mutated and totally hilarious things I have ever seen...
But getting to the topic at hand. Todd, first off you are a great guy that is super accomplished and I wish you the best. That whole group is a great selection and I know you are going to do great. From what I just heard from my buddy who has been in the area many times, there is a big danger of falling rock due to the geology. One of the main dangers is sleeping on the banks at night, as rocks are constantly breaking off and rolling down. Pick your camp spots w/ that in mind...
Just be sure to stay safe.
