Also: BG's raft sank. DC & CL's rafts sank. If they are too dumb to take a hint - well, a grateful human race thanks you.
I once sat down and checked the backgrounds of about fifty or so of our recent SAR victims. The common denominator was inexperience, not necessarily low intelligence. i rather suspect that the IQs in that sample were fairly representative of the population as a whole; one of our fatalities was a PhD candidate who had just successfully concluded his oral exams that afternoon.
I myself was once inexperienced; as a matter of fact, I nearly died on my first significant hike into mountainous country. I consider myself reasonably intelligent, but I was certainly unaware of some very basic outdoor safety principles. Since then I have gone on to a long and happy time working and recreating in mountains, deserts, and oceans. Along the way I have been active in SAR and also in our efforts to reach out and give inexperienced people some understanding of the hazards that exist out there.
Now BG and his ilk are certainly experienced and know their stuff; an earlier poster mentioned his outdoor manual. I agree with him that the book is utterly unlike his shows. It contains good basic stuff. So why do these guys demonstrate zany antics that are likely to get you killed? The dirty little secret is that real survival tactics can be rather boring. It is much more dramatic to jump forty feet down a waterfall into unknown waters than backtrack and find a route that will allow you to walk down. You need to jazz up the action to get good ratings and if it means demonstrating unsafe antics, well that's life. To me, there is something immoral about that approach. But we live in a capitalist society and they are making money, so everything is just fine.
Bottom line. Good intelligent people get into trouble frequently because they just haven't been informed about basic principles. Those who have this knowledge really ought to be getting the word out rather than demonstrating and promoting unsafe practices. Enough already. End of rant.
