Shouldn't that be 'are neither', not 'is neither'...?
Is there a suitable warning sign about pedants?
I saw a programme about the first climb of the Old Man, is was covered live on the BBC, and in those days (60's I think), an outside broadcast required about 50 lorries of technical equipment, all of which had to be driven up there and parked (and then dragged out when it sank in the mud).
