Maggie looks wonderful. I would love to have a couple of horses one day...there are SO many wonderful horses in the UK that just get palmed off by people or abandoned; I'd like to rescue a couple. But, like you, I have a lack of experience - my husband rode when he was a kid but aside from that, we know nothing.
Animals are also sooo good for the soul, especially those with extra intelligence and emotion like horses. I can imagine that Luke gets A LOT out of just being around Maggie.
Right...off to watch the coming home video!
