I'm a huge fan of dressage! Don't get me wrong, I'm a hunter/jumper girl at heart and don't plan on ever joining the "black tack" club but I do dressage on every horse I ride. It makes every horse I ride more "rideable" and significantly improves strength/balance, etc. Dressage is all about balance, precision, suppleness, being soft and in tune with your horse. Like JDI said, what discipline doesn't need that? I think it's pretty incredible when you can influence where each of your horse's 4 legs are and when, how he holds his body, where his balance, is, etc! While it may not have the fast paced excitement of something like jumpers, it can be just as exciting depending on what your goals are. To me, getting a horse to take his first quality leg yield step, or learn to submit to the bit is just as satisfying as going double clear in a tricky course. (okay, almost as satisfying :)).
