You know, one must be careful with sterotypes... Back in the late 80's and early 90's I was involved with ecotourism. Sure, when you look at a group, the first instinct will lead you to believe the odds are the "soft" types will be the ones which will get in to trouble. Pale overweight urbanoids, quite often carrying lots of gadgets and gizmos. Yes, you may be right and they may be the ones who will not notice the nest of wasps, lose ballance, become too tired to walk, etc. However, usually they tend to follow the rules and the orders because they know they have limits. Quite often the troublemaker turned out to be that athletic person who's used to hiking, clibing, spelunking, etc. (or claims to be used to it). He/she is so convinced of his/hers awessomeness that believes to be above the rules and with über skills, the real life Tarzan. That's one of the reasons why I believe getting hurt in field expeditions is not the main bigfootery problem. Taking in to account the average profile of the footer, based on the images I saw... I doubt they will get themselves in to more problems than the average hunters, hikers, visitors of national parks, etc. will, because **** happens and sometimes its impossible to avoid people from taking part in to a "Jackass" act...
Oh yes, the worse types are the pale overweight urbanoids, quite often carrying lots of gadgets and gizmos which are so convinced of his/hers awessomeness that they believe to be above the rules and have über skills... Make them suffer, they deserve it, I say.
The real problem of bigfootery is fraud. It doesn't matter if the fraudster is taking just some cents from the sucker. Its wrong, its fraud. And also remember, extract a few cents from lots of people and you'll make a lot of money. Oh, and yes, making money out of bigfoot tours is IMHO fraud too. Even if people have fun at them, its a fraud, because someone is making money out of a lie, a fraud, a hoax - the assumption that bigfoots are real and there's a chance you'll see one at their tour.
