I would want to know how many survival incidents he has personally experienced - scrapes, close calls, etc. What other experiences might qualify him to teach this school?

Apparently there is not a formal certifying body like the American Society of Survival Schools (ASSS) to provide vetting...

BTW, what "part of nature has been made safe for tourists"? Are you referring to national parks and the like. If so, Iamnotso sure that is accurate - plenty of people get into trouble there...
