notags2, thanks for the PM I did reply.
I do remember talking to outfitters many years ago that had half-draft horses. I have considered looking for some of them. Not sure I am aware of any that use full draft, and frankly it would be fun to seem my buddy load on one of those. Not sure his ankles could take much saddle time, but some.
I appreciate the idea of not gaming the definition of "handicapped", but let's leave any decision on who is handicapped to the experts and not make generalizations based on what I have described so far, I certainly didn't ask for opinions on what should be considered "handicapped". FWIW, by buddy's Orthopedic surgeon advised him 6 years ago he needed to fuse his ankles due to injuries he sustained in the line of duty as a Corrections Officer. He has chosen not to, forgoing benefits he could qualify for, because he likes his work. He decided ankles with zero range of motion and even less ability to hunt is much worse than dealing with the pain he has now. So it's a little more than just being "big and overweight".
