What happened to my beloved mare and foal? Very sad story. We went on "home leave" for the summer, and I sent my mare and colt to a big horse farm to live in a pasture since no one would be riding her. The young horse got tangled in barbed wire and was lame when we got back. Then my dad was transferred to NASA headquarters in Greenbelt, MD, so we had to move back to the US.
My mom sold my mare to a family who, I was told, rode the crap out of her and did not value her. We gave the lame young colt to a missionary family who took him to a missionary compound in some remote part of Ecuador. They kept up with me for several years, completed the colt's training, rode him, and loved him. I lost track of the mare. I always convinced myself that my mare was so amazing and wonderful that she landed in a good place after those bad owners. Americans in Ecuador only stayed a couple of years and usually sold their beloved horses to new Americans who had arrived. So I am going to think that my mare, whom everyone adored, ended up in a good place after that bad family.
