Would it be a good idea, who knows, but it's 50 miles from where I am in the northern conurbation of PBO (an hour drive at least) so it's not really close. Leicester is actually slightly closer to Brafield than that at 48 miles, and Oxford closer still at 45 miles. Brafield may be a potential venue for a team for either Northampton or Milton Keynes, but I think it would be too big a stretch to call it Peterborough.
