As we started to leave the barn area, he turned on a dime and tried to go home. I spun him back around. He walked sideways, backwards, sideways, and ended right back into forward position. We made several of these circles. He jumped around, backed up, side stepped, and reared (not very high, just enough to show he was cranky). I tried to shorten my reins, lengthen my reins, have one long, one short. I tried to just make him circle, but he wouldn't without somehow maneuvering toward the barn. Eventually, I gave up for both our safety and took him back and worked him in the arena for a bit before just walking around the area that surrounded the barn.
I'm considering walking him out there on foot, halter and lead. If there's not too much fighting, I'll do it again with him wearing tack and mount him out there and see where it takes me, but I'm really stumped. I've never fought with a horse so hard and didn't have some kind of break through, if even for a few seconds. He was freaking determined!
