Wish there had been one on the canal we had a holiday on,first my 8 year old son fell off the boat into the water,his dad had to jump in,didnt know at the time the water level was quite low owing to a hot summer,i didnt know how to steer the boat so had to open all the locks not happy when iwould open a lock, mac would go through people behind would follow,and laeve me to close it as i had oppened it they should have closed it
