How to convince my parents to let me go to camp?

I'm 13 and I've always been crazy about horses. I wanted to go to an overnight camp. I knew I could learn a lot and make new friends. But money's really tight right now. I just want to /try/ it this one year! Just to see what it's like. I live in Nebraska and the camp's in Ohio. I know it's really far away, but when I looked through their website and read the comments, I knew it'd be worth it. I at least want them to think about it. Tuition's $950. It sounds expensive, but for all that they offer, you'd get your money's worth. I just want to see what it's like. And next year I'm going to start de-teling which pays hundreds of dollars. Then I could pay for most of it. It's been my dream to jump a horse for a loooong time. And you get to ride for at least 3 hours a day. I haven't really asked my parents about it yet because I'm afraid I'll say the wrong thing. The camp is called Falcon Camp, by the way. (falconcamp.com) Does anyone know how I can convince my parents? I can't put it into words how much I want to go. Begging doesn't work on my parents like it does to others. I'm not a spoiled girl. Please help me! And please no negative comments about anything. I know it's expensive but I just want to try it. Just this once. I'll add more details if you need them.
