Didn't forget plugs. Just floated under a tree that tipped it and took in water over the side. It sunk like a rock. I now put a rope on the machine and pull it over empty if we can get someone across safe. We were on a river last year where some guys were trying to carry an Argo in a boat. Boat sunk with the load to high and the Argo floated about two miles before it got hung up on gravel. Water was very fast and about 12 feet deep where they went in. Always fun!
