I have a great story. Moving 2 sleds in an enclosed trailer. I forgot to raise the front jack. Just started the trip and went over a bridge that spanned over a highway. As soon as I hit the bridge the trailer popped off the ball. The trailer crossed the road and stopped just short of a car that contained 1 woman driver and 2 children in the back seat. 1 sled broke the tie downs and went right though the front of the trailer, ran up the ladies hood and the front ski bounced off her windshield. God was with me that day. The trailer didn't roll off the bridge onto the expressway, the sled didn't crash through the ladies window. I had safety cables on the taller that were old and rotted out, they spanned immediately. To top that off, we were hosting an end of season party for my daughter's soccer team. Lots of inquisitive looks from parents picking up their kids. Thankfully, my wife new the lady and I just had to pay to repair her car.
