Surprisingly the control tower on the airfield lasted a long time.
It was obviously something of a landmark until quite late on in Oldton's existence, since it crops up in a fairly recent picture of the village pond, itself a rather desultory sight.
Paul (a man who is full of theories) wonders whether the pond with its attendant ducks may be one way of finding out more about my disappeared town. Find an Oldton duck, he supposes, and I can start to identify the chemical code that will unlock the precise location of Oldton.
This presumes that ducks are not susceptible to toxoplasma gondii or a similar parasite that might have forced the birds to drown themselves long ago.
