In response to these concerns, a number of cities and states, mostly in the eastern half of the United States, have passed ordinances and laws governing rodeo. Pittsburgh, for example, specifically prohibits electric prods or shocking devices, flank or bucking straps, wire tie-downs, and sharpened or fixed spurs or rowels. Pittsburgh also requires humane officers be provided access to any and all areas where animals may go—specifically pens, chutes, and injury pens. The state of Rhode Island has banned tie-down roping and certain other practices.Other locales have similar ordinances and laws.
