I agree the cut can evolve but at the moment it's running the real risk of becoming a theme park with no relevance to history and why things are as they are.
Seeing how things changed over time as motor boats came along...locks were widend...material handling changed etc I agree is very interesting....having fences and signs erected all over the place because the human race appears to be losing all common sense is both a detrement to the present waterways enviroment and will mean we slowly lose the reason of how & why structures were originally constructed as they are.
