I raised a good running horse once named him On The Nose, had lot's of potential sold off three 1/4 shares and sent him to a trainer in Ok. He got hurt in the trainers barn the first night there, was never able to run after that.
Stable boy threw hay down into his stall at 3:00 am in his first night in a new barn and he burst threw two gates and one fence.
Moral don't change brands of fuel the night before race day,
