Usually, the Wichita Wagonmasters cook large amounts of chili only in September for the popular Wichita Wagonmaster’s Downtown Chili Cookoff . On Saturday, Feb. 25, the Wagonmasters will be putting on a chili feed in Old Town Square , Second and Mead, with the goal of raising money to benefit Wichita police Officer Brian Arterburn, who suffered injuries to his chest, abdomen and brain after being run over by a stolen car on on Feb. 7. He’s still in critical condition at a local hospital.
