To my knowledge, only one. “Dual Survival” had one episode where Cody pretended to have a broken leg. One theme repeated over and over again was to not separate. Of course I imagine that’s always a cardinal rule, but probably more so in that situation.
I have been hiking that area for over 30 years. The trails are well marked and normally plenty of hikers. When you go off trail unprepared that’s when trouble happens. It is thick in brush with lots of ravines.
The hikers are lucky they did not go from June to October or weren’t taken out by a mountain lion or coyotes.
