Oh, my arena has been my greatest accomplishment yet, lol. I've been asking for one forever, but we only have 13 acres and he doesn't want to sacrifice any grass or mess up his paddocks with an empty space, as he calls it.
Bailing twine is like the duct tape of the horse world, lol. I have made side reins, ties downs, curb straps, held tack together, made halters...I've even used it to ride once. At a place I boarded, my horse was WAY in the back pasture and I had to walk to him. I had the twine in my pocket so I could lead him back with it, but he couldn't see it like a halter and run away. I didn't feel like walking back to the barn so I just ran it through his mouth and I rode him back, Indian style. We've made jumps out of anything and everything you could imagine. I actually miss the days that I boarded, and the things we used to come up with!
