If you've ever had a Rice Krispies treat, you can thank a guy from the tiny town Arminto, Wyoming. On May 14, 1918, Hazime Fukuda received a patent for the first rice cereal. His method was later adapted by Kellogg's and has since spawned dozens of popular products.
In the early 20th century, there were 6 million sheep in the Cowboy State, nearly 50 sheep for every man, woman, and child. Many of them ended up at the stockyards in Arminto.
