For anyone who enjoys horses, even just a little bit, the place to be in late October is the U.S. National Arabian and Half-Arabian Championship Horse Show, which takes place in Tulsa at Expo Square from Oct. 19-27. There will be literally hundreds of different contests featuring Arabian horses, which are generally considered the most beautiful, pleasant and athletic breed. The horses will compete in various activities that judge them on appearance, breeding, attitude and personality, and physical agility, in both amateur and professional classes, over the course of the event.
