If the issue today in some people's eyes is the need for this community in Greater York to be one hundred percent self sufficient then perhaps we really ought to go pack up and er go home, er because there's no way that er a settlement that one could envisage in Greater York or perhaps anywhere else can be a hundred percent self sufficiency, self sufficient, you're not going to get a shopping mall, you'd be unlikely to get a a major touring theatre, so you cannot aim for a hundred percent self sufficiency, you aim for what is appropriate for the size of the community and particularly its relationship to existing settlements er in the general area.
