Hi Derek, I have only been on the cats. Not the old green ferries, never seen it that rough either!
My son and his partner like to look at the flora and fauna, which I am sure is very nice but put me near an old crane or loco I can climb onto and I am happy.
I did have an enjoyable day last year showing my son around the York railway museum. I had to explain some of the mechanical workings which I later saw him checking with a museum attendant, made me smile! We old b*****s still know a thing or two even the ones without PhD's.
He is good company though.
I return in mid Feb for another 5 weeks of extra summer.
regards Roy
