Almost everyone else here seems relatively normal for horse people. There's a ranch a bit further down that raises the prettiest paints I've ever seen. The people two houses down on my left have Belgians and most everyone else has Quarter Horses. They're all in good fencing, good health and happy. Then there's across the street... and well... yeah.
Do NOT feel bad, you are not responsible for that horse.
You have to think of the safety of your own horse.
Lets all just hope that he is going on to a much better home, sounds like almost any where would be!
It is not his fault he behaved the way he was, as others all ready so eloquently put it, his owner was an idiot.
