Bilger kicks off the tour from his hometown in Oklahoma, where he "noodles"--thrashes a limb around in catfish-thick waters--hoping to land a fabled 80-pound monster with his bare hands. In Louisiana he challenges the misgivings any nonenthusiast might have about cockfighting. Even though it's illegal in most of the country, the bloodsport is thriving in the Bayou State, replete with trade magazines, well-produced venues, and American Kennel Club-worthy breeding strategies. The same passion for efficiency goes into the moonshining business, where Bilger is taken under the wing of one of the few shiners willing to lead him through his sourmash operation. A few nights later, however, Bilger is on the other side, on a raid with the local sheriff. Squirrel-brain consumption is still popular in hamlets throughout Kentucky, even after a report published in the New England Journal of Medicine blamed a neurological disease on the dish. Frog legs, one Georgia entrepreneur claims, will soon replace chicken, and southern cooking--the kind that features chitlins, pigs feet, and collards--has become haute cuisine in Atlanta. Back in Oklahoma, Bilger connects with a coonhound trainer during a long night's raccoon chase, and he follows the success of a backwoods marble team who shaped their shooters in the granite-strewn streams of Tennessee. Bilger treats each eccentric character with a distant respect and hints at the melancholy of losing tradition, no matter how bizarre. --Lolly Merrell
