Wooden escalator - vortex tunnel.

As I've been inside most of today and lacking the imagination to see anything around my flat interesting enough to blip, I thought I would post a final shot from our tunnel walk earlier on in the week. I believe this wooden escalator is one of the longest, if not the longest, of its type left in the country.
Probably be a while before we go there again, although I might take a bike ride through it on the way to Sunderland.
