The Leeds-Liverpool Canal and the Wigan Flight, in particular, are an endless source of photo opportunities. Now and again, it is possible to come across a boat just entering (or leaving) a lock with all the people who are working the lock gates in shot, and to have them interacting.
I love the atmosphere of the first shot and the interactions of the second shot. The third shot is a bit of an experiment with a 20mm lens, and it probably confirms I need to practise a bit more.
