And, the Fort Worth Herd - See cowboys run a cattle herd right through the Stockyards. It goes twice daily. http://www.fortworthherd.com/walking in the Stockyards - checking out all the Western themed stores, hanging out in various dusty saloons, and seeing cowboy shootouts in the middle of the street - there's a place for rodeos too.
