Took the boat's down and put it in storage this morning. I will go back and get it the first Saturday in April. We can testify to the crossing the chains under the tongue of the boat or any trailer. My friend has his boat in the same place as I do. We travel together incase one of us has any trouble. Then I back his boat into the shed for him. His wife hooked his boat to the ball on the back of their Jeep. She didn't get the hitch all the way on the ball and about half way down to storage his boat came off the hitch and was lucky enough we had to slow down to go through a small town. When he stepped on the brake the boat jumped up in the air and then down to the ground and then just started whipping from side to side. He was lucky that he got it stopped before it did too much damage. The tongue hit the back of the bumper and dented it a little but was really lucky it didn't come off the Jeep. EB
