Did you happen to see the episode where she got her sled sideways on the ice and rolled it? Apparently the shows producer asked her to flip the sled intentionally, to add a little extra high drama to the segment. Anyway, she was injured in the stunt, and had to be airlifted out for medical treatment. So much for "reality".
Just my opinion, but Life Below Zero has a lot of fairly obvious BS in the way they (the producers) portray things. Don't get me started on Glenn Villeneuve... that guy seems to be operating with more than a few bricks shy of a full load.
Mountain Men is one of the few "Alaskan" shows that I find interesting enough to watch... Marty, Tom, and Morgan seem legit, both in their efforts and how they allow themselves to be portrayed. The Last Alaskans has also been pretty decent, along with that show based up on the Tanana River... Yukon Men.
