Well the barn doors are shut and I was right there with him, he dosent even try to get loose.
Its still a bad idea. Since those cross ties don't have quick release hooks on them and you are using a rope halter... it will be harder for the horse to break out of the ties. I've seen horses flip over backwards in the cross ties due to using rope halters (they couldn't break them and they panicked even more)... and the outcome of their horse's head hitting the stable floor isn't pretty for any of them.
One reason why I don't use cross ties haha.
