I got a horse now what do I do?

We have survived almost one year with the horses. Let me back up a bit to tell you how this all happened. Sky decided she wanted to take some lessons and some lessons turned into us getting a horse. Well...that horse needed a friend and this is how the story begins. Our first horse Bo was an old timer he was good to learn how to groom and feed but he didn't like the whole let me get on your back and ride you thing so he was sold to a wonderful woman who just wanted a pet. Bo needed a friend when he was here and the woman Sky was doing lessons with needed a home for a young gelding she had who could no longer jump but was full of spunk. So "A Kodak Moment " came to live with us. He is a super cute pony who thinks everything may eat him but we are getting there. In Jan. we bought "Lakota Blue Spirit" a Buckskin gelding who has NOOOO ground manners so right now he is living with our trianer. Ok so thats a bit of the story.
