If manhood is demonstrated by running away from camp and then, days later, from home (Mom antes up the spending money), hitching up and down the East coast, and finally faking illness so that the hospital will call home. . . then Pat Burke's stint at a macho Vermont survival camp really does make a man of him. Everyone Pat knows, from his private eye father ""Beagle"" Burke, to Gil, the kid who wants ""to be ready"" for the gang on his street, seems to value physical toughness above all else, so maybe it's not impossible that a lifelong weakling could shape up after a few short weeks of hiking and 5:30 reveilles. But like ""Beagle"" one tends to think that ""nobody changes that fast,"" and even if Pat's days on the road could be a step up from passive rebellion that doesn't erase the queasy feeling that everyone concerned is kidding himself.
