Every spring, nearly 4,000 Bonnie and Clyde aficionados head to Gibsland, La., to witness the re-enactment of the fateful 1934 shootout that marked the bloody end for the Romeo and Juliet of armed robbery and their two-year crime spree, which left at least 12 people dead.
In Lake City, Colo., they celebrate Alferd Packer Days to commemorate the trial of the first American convicted on cannibalism charges.
In the rugged winter of 1873, Packer was trapped in Colorado's San Juan Mountains along with five other prospectors. He emerged 65 days later looking suspiciously plump.
Now, the mountain marks the event with a two-day celebration, with coffin races, bone-throwing contests, and excursions to Dead Men's Gulch, where Packer's victims were exhumed.
The strange fete eventually inspired "South Park" creators Matt Stone and Trey Parker.
While they were students at the University of Colorado at Boulder, the duo collaborated on their first project, "Cannibal: A Musical," a 1996 feature film that promised, "All Singing! All Dancing! All Flesh Eating!"
