I am getting my horse soon, and I am planning on teaching him to jump. Problem, where I will board him, and yes it is the best and only option, they are all western people, and all they have that I could jump are barrels, which aren't really ideal for learning. So how can I cheaply, and easily make home made jumps? They need to be safe for jumping and using as ground poles. I don't think they would let me use their hay bales either. So, any one got any ideas?
