Thank you all for your replies! Boomer is normally really good, he just gets his "winter spunk moments", but if you are firm, calm, and patient with him, he snaps out of it. Also, if you half-halt him, and ask him to stop, and collect himself, he will go really well for you. From my time with him, he was really good, and willing to please, you just have to be clear about what you are asking him to do. He tries so hard :), but sometimes he just gets too excited.
, your point makes lots of sense, and I certainly don't want something to go wrong with him. As long as you are firm with Boomer, he will go for you, as he just needs that extra bit of encouragement. I have been with my current instructor for two years, and before that I was with another one for 4 years, but I am now moving to an eventing barn. Not the greatest timing, but I think I *could* make it work. I agree with you - the girl who leased him last year recommended gymnastics and lunging for Boomer. He is not ridden all summer, and he gets the rest of the year un-ridden, undisturbed by humans in a free running herd with 150 + horses on hundreds of acres, if no one takes him home. I came the first session, and the girl took him back in May, so no one rode him from that point on. My first ride on him was his first ride back at my camp. Believe it or not, he is actually a dream to flat! He can collect his trot so nicely that it feels almost like a walk, and I am working on his canter. He even knows his flying leads! (The girl who took him home taught him that). Last year's leaser also jumped him in gymnastics, and courses, I think her highest jump was 3'3" on him, but I am not certain... not extremely relevant anyway.
I am 13 :) I will be boarding my horse at an eventing barn about twenty minutes away from my house. I will have lots of horse people around to help me, if needed. Hopefully I will be able to tell if he was lame (that is one of my fears... him being lame and me pushing him), although he tends to "tell me" if something is wrong. At camp, because the farrier for whatever strange reason forgot to trim his feet, he became unsound, and as I was leading him to the barn, he kept stopping, not to graze, but just to stand there. I would be willing to work off some of my board, and make some money in other methods, for example, I am launching my business in September, and I am hoping to pay off some of my expenses using that.
Thank you all for your honest opinions, they are really appreciated :)
