It’s hard for me to verbalize how big an impact this documentary has had on my life. Among other things, it’s made me quit my job once and risk it at least once more. I am smiling so wide right now, just listening to it play in the background as I post this blog. So adventure lovers, sit back (or better yet, bake yourself a batch of sourdough bread and then sit back), relax and watch these four adventurers take the journey of a lifetime down one of the world’s greatest rivers.
