Alligator farms, tigers at truck stops, homes of historical personages and monuments of kitsch, from giant animals to theme villages, grew up with and along American highways to service and amuse its mobile families. Offering respite for children and drivers, with souvenirs, fast food and motel rooms, they also reflect generations and class in road development. Those huddled along slow, two-lane roads seem quaint and crude beside the sophisticated advertising of regional tourist boards, highway hotels and major theme parks dominating interstate landscapes. Countless guides exist to both serious and tacky stops somewhere between democracy and chaos.
