interesting show today on how some zoos try to enhance the lives of their captive animals go me tho thinking about how we could enhance the lives of our horses. Even if on 40 acres, we still hold them captive. I'd be interested in hearing your ideas. I'll start with one of mine - since I have clay soil I'll soak a bare area larger than a horse as they love to roll in it. The clay when dried provides protection from flies. The soupier the dirt the better.
