In reply to Sleepymrsp:
I didn't even think that wall was in use any more, I really can't imagine they have the staff to man it. I never head of it being used anyway.
I usually get the train to hornbeam park from horsforth, which is an easy enough journey, and hcc is just down the road from there.
Alternatively, leeds wall can be done in a couple of bus legs.
Where about are you?
