Why do we go to shows? There are four reasons.
Why we show horses in general is a subject for much deeper study. Why do we want to spend hundreds, if not thousands, of dollars taking a 1200-pound prey animal to a scary environment all so that someone in a little box can tell us why we're not perfect at it, and maybe earn a few bucks' worth of ribbon and, maybe, if we're lucky, some delightful GMO glassware? An excellent question, and certainly one that proves the Equestrian Psychosis.
