I'm going to be spending the summer away from my most beloved horses here in Washington State. I'll be with my grandad in Alabama. He's got 300 acres of land, an intoxicating thing for one who rides horses. Ever seeking to get my horse-fix, I have made contact with one of his neighbors who has horses. She just recieved two horses free of charge. One is an older mare, and the other is her colt... who by the sound of things has clubfoot. Being free, these horses either haven't been started at all or it's been quite a while since they were ridden. This said, she has agreed to loan me one of the two to play with the entire summer.
My question is, where should I start with this informal training and how far should I go? I'm familiar with tons of groundwork and desensitizing games and would like the opportunity to work on my lunging and long lining techniques. Unfortunately, I won't have an actual arena or round pen to work in. Should I even consider eventually backing one of them? I am assuming that a great deal of this will be based on what I discover about the training they may have already had and their temperaments.
