It is an interesting article and a complicated situation. When I saw this link, I was thinking more along the lines of Zudnick(sp?) from the old ski movies, but this is quite different. As an animal rights advocate, I wonder how the service animals feel about this? Are they terrified? What happens to them if their human falls on them? What happens if the animal escapes and causes another skier/boarder to be injured? I also know there are lots of people who are nervous around dogs, so how does that factor in? I have also experienced first-hand people who are abusing the "emotional support animal" practice, so I can definitely see this getting out of hand. Ultimately, if it truly allows people with disabilities to experience a more enriching life, then I am fine with it.
