Welcome aboard CF, lee113. I had to refresh my memory of where Wirral is
There will be
someone around (or some group) that will know the state of the canals between you and Grimsby. The UK is awash with folk who know all about walks, canal. railways etc. You will just have to hunt them out to confirm the current
draft of the canals /locks in question.
As for the trip itself, it should be easy. Some simple motoring and docking
skills plus discovering how the locks operate. Once you have done the first couple, you will just be repeating the same skills another 88 times
Assuming you have the time (and you might not have to complete the trip in one go) and a mate or two will to join you along the way or at least for the first five or ten locks, you will have a great time.
Crikey, I want to buy a airfare to Liverpool just thinking about it
