Reading Marty Irby's letter to the editor, I didn't know what "soring" was. It turns out to be the use of chemicals, pressure and devices designed to cause pain to horses when they step on their front feet and legs. This then causes them to lift them up quickly when they touch the ground, resulting in "high stepping." The Horse Protection Act of 1970 prohibits these practices in the U.S., so it appears that all that should be needed is enforcement of a law that already exists. This cruel practice should have gone out with blinders and removing cats' claws. Pressure from within the sport itself should help stop it, together with prosecution of a statute already on the books since 1970. Why that hasn't happened is puzzling.
