I liked the sign, below. And the horses, who seemed to enjoy posing for photos. ‘Equine activities’ sounds intriguingly open. So when the horse kicks you, bites you, or throws you off and you break your neck, it seems the thing to say is that horses will be horses. What if the horse acts in an un-horselike way? Say, it kisses you and you get horse flu or something of that sort? Is that an ‘extrinsic risk’ of the horse? And what about the ‘inherent risks’ of humans? Or their ability to ask silly questions?
