Dr. Kevin, if nothing else, is a music aficionado. He's big on American classics, and he was pondering the old folk standard "Big Rock Candy Mountain."  He soon realized that in its original writing, the Big Rock Candy Mountain seems like a pretty sweet place if you're an alcoholic vagrant.  If you're one of the millions of kids who hear the watered down versions of the song, though, you're only really appreciating the Candy.  The Big Candy.  The Big Rock Candy.  Like all magical places, however, there are also dangers.
