I really believe for some, like myself, it's "in the blood" so-to-speak. It certainly is fun (assuming one is not having one of those dangerous, fear -filled moments on horseback). I'm not sure I can adequately describe the fun or feeling in writing. It's definitely one of those things that must be experienced to be appreciated. But...once the thrill of cantering through an open field, going over a jump or through a stream, ridng such movements as passage or piaffe, feeling a soft warm muzzle on your cheek, hearing them nicker to you when you walk in the barn and in general feeling the movement and power of the horse beneath you and becoming one with that animal where you truly are able to speak and understand each other is paramount to anything else I've ever known.
