The May 27, 1922 issue of The Evening Independent carried a story about moonshiners wearing "cow shoes" to trick revenuers -- rather than leaving suspicious footprints leading up to their secret stills, they'd leave innocent-looking hoofprints in the dirt and grass. The New Yorker's "Photo Booth" had a good snap of one of the shoes (above).
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
