And Bear gives bad advise. If you are lost/stranded and ANYONE know's your travel plan (which someone should), stay put. If you need to move to get essential resources like water, then do that and leave marks along the way...then stay with your resources. Using a cold river to travel until you are near exhaustion or hyperthermia is generally a BAD practice as well. So is shooting rapids in said river holding onto a log. Bear does offer little helpful nuggets mixed in there but if you know enough to discern them from all the rest, then you don't need Bear's advise so much. It is just entertainment. I always look forward to the disgusting food item/Fear Factor dining moment in each episode.
I have a lot of respect for Les Stroud on the other hand. He makes mistakes but he and we learn from them. Dude knows way more than I do in general but he blows it on shelters it seems to me.
