Here's the backstory. A long time ago in a faraway place, there was a company that owned stockyards. A stockyard is a place where cattle are auctioned off to buyers. Ranchers drive their cattle by horse, or train, or truck to the stockyard at pre-determined dates when auctions are held. Cattle buyers come and purchase the ingredients for your burgers and steaks and the ranchers return home without cattle, but with pockets full of cash.
The company was established in the 1870s in Oklahoma. The date and place invoke images of cowboys and Indians, saloons and western movies. Those days are long gone and the company now consists of three things, their Oklahoma stockyard that's still transacting cattle, a plot of empty land near St. Louis, and an ownership interest in a golf course.
