Here's the clearest example I've seen of why anyone looking for a guide needs to get references and check them before continuing past the initial contact.
Clueless guide sentenced for defrauding hunters. The lead for the news article will give you a clue about "Clueless": "KENAI -- Dozens of hoodwinked hunters bagged a measure of justice Friday in the case of the wilderness guide who set himself on fire because he couldn't work a camp stove."
No, he wasn't a guide. But he took in more than $100k from unsuspecting victims. Some of them were probably lucky they didn't die as a consequence of his "guiding."
