Another point which hasn't been taken up, despite us being invited to is why is the Greater York area the size that it is, and this is a point that the Senior Inspector raised, er in other towns and cities, I'm thinking particularly of Exeter for example, the districts have looked at supplying their city based land supply problems on a journey to work area, now that area would be significantly greater than we're looking at here, and it seems to me in this location er where we see a potential abundance of supply beyond the strict confines of the Greater York area is a very apposite question to ask, why is the Greater York area the area that it is?
