These matters are regularly 'debated' in letters to the editor, but for those who would be interested in learning more about the context of these decisions and in discussing them with others, the Oxford University Department for Continuing Education is running a course on the Theory and Practice of Town and Country Planning starting in October (details on www.conted.ox.ac.uk or from tel. 01865 280893).
