Jim,
My wife Pat was born and raised on a farm, and her famiily still runs a 400 acre dairy farm in Shelby county just this side of Shelbyville Indiana. To Pat and I'm sure her four brothers as well, a horse is a pet, no different then a dog or cat. Ernie, pat's dad kept several just to have around, to feed sugar cubes and pat on the head once in a while.
I don't think they were ever ridden by any of her family until we got married and I came into the picture. To be honest I've never been real attached to any of the horses I've owned and there have been many, and as you probably know you don't really own a horse because they all have this complex about humans and most of them just want to eat and sleep.
Now, after saying that, I do have this one horse in particular that I have grown rather fond of and I think it's because he has the same disposition that I do and just about the same temperment, thats the one I've added to my avatar. McGregor is a Wyoming mustang I bought from the BLM when he was just over two years old, he's almost eight now. He doesn't like other horses, he's not agressive towards them, he just doesn't like them. If you are out in the pasture doing chores he will follow you around until you climb on his back and spend some time with him, while the other horses head in the opposite direction, he thinks he is human.......
Good horse, real smart as horses go, a lot smarter then most humans and dogs I know.......
