States and cities frustrated by gamblers spending their money elsewhere are putting casinos in or near major cities to maximize tax revenue. "We're sick of people from Wichita driving through our county on the way to casinos in Oklahoma," says Janis Hellard, economic development director in Sumner County, Kan., near Wichita. "We want some of the action." Her county is one of four places in Kansas recently authorized to have casinos, although none has been built yet.
