In the 1800s, when the American West was first opened, the early pioneers were offered free land east of the Rockies.
But to ensure fairness, they could only stake out forty acres after a race to the region on a specific date and time.

They were called “Sooners” because they arrived “sooner” than those who obeyed the law.
