The U.S. government decided to buy Oklahoma from the Red Skins in order to open up this territory to colonization. On 22 April 1889 the signal was given of the rush on Oklahoma. Lucky Luke was the man who would oversee this historic operation. As a government representative, Lucky Luke would hunt down cheaters, arrest thieves, ban the guns of Boomville, organize elections... Until the settlers decided to leave this much too arid territory to their liking!
