Mini Horses as Guide Animals?

Would you welcome a miniature horse serving as a guide animal in your place of business? You may very well not have much of a choice as the new regulations of the Americans with Disabilities Act are going into effect. http://www.ada.gov/service_animals_2010.htm It might be a good idea to start thinking along the lines of retrofitting your establishment with a hitching post.

There are those in favor of this no doubt because it will mean a possible increase in their business of providing service mini horses. http://www.guidehorse.com/ Then their are those who present the opposite opinion. http://www.guidehorseno.com/summary.html

There does not seem to be a perfect solution for showing compassion for disabled persons. I wonder why other humans couldn't serve as guide attendants? There's lots of us and some of us are fairly intelligent and trainable. We need some more brainstorming on this methinks. What thinks you?
