Why not Duxford and Shuttleworth

Duxford is on the 5th of October as is the Shuttleworth Autumn show. Why does the Vulcan not do both, Duxford then Old Warden. Lets face it they are only 30 miles apart and the vulcan has to fly, home so Old Wardens on the way ish. This way 2 shows =1 flight twice the amount of people to see her. More bang for her buck so to speak. Is it only me who thinks like this?
