Al R - I agree Alconbury looks good. Weren't they planning to develop it as a freight hub after the spams left? Dunno wot happened to that plan.
Good road access, except for the last mile, good runways and facilities. Close to A1/A14 Interchange and so M11 and easy access to several other Motorways. Only about 5 miles away from Huntingdon Railway Stn (which is on the East Coast main line from London to Edinburgh).
