Went for a chug down the Leeds Liverpool canal last Sunday with members from the Mercedes Benz Club and had Sunday Lunch on board a barge/motor vessel/pleasure cruiser. Good food and good company. What crossed my mind though was. Do children of today get taught just how deep canal locks are and how to behave around them? As we dropped down through the system at "Top Locks" Whittle le Woods (ST 4 you have been there) It struck me how sheer the walls of the locks are and how greasy the ladders rungs are. Not a lot of chance of getting out of there if you are on your own. Certainly our grandchildren have not yet been taught about them (very soon to be amended) through school or good grandparenting.
