I mentioned the Arcade in Manchester to someone only recently Graham but didn't realise it was still there. I suppose the good thing about these installations [as said] is the preservation and relative lack of damage. It could be worse. Even Huniken set fire to a huge pile of TV's
.
The Yorkshire Sculpture Park is a good place to visit even when there are no technical exhibits. It's now part of a triangle that includes the Museum in Leeds centre and the New Hepworth Museum which I've not got to yet.
There is also a Coal Mine Museum relatively close, near Wakefield I think!
