I got this book from my local library, but I understand that it's also sold at Yellowstone itself. This is probably a public service. But the sad truth is that the people who really need to see it, who think that the boardwalks around hot geysers are just suggestions, that the bears must be tame and look so terribly hungry, or that it would be fun to swim just above the falls are exactly the people who won't read and absorb the lessons of this book. For a book about horrible ways that people can die, it's remarkably free from sensationalism. The author used to work at Yellowstone, so he understands what the park is really like and a little of why people do the ill-advised things that can kill them. And the sad fact is that most of the deaths in this book, even the ones by natural causes, could have been avoided entirely. Certainly creepy, and if I ever do get out to Yellowstone it'll probably leave me slightly freaked out.
