There's quite a few reminders of CD left if you know what you're looking at. Viscount Road follows the line of the southern peri track, plus the road which once formed the road to Lockington is still extant. There was something here on the aerial shot but I can't make out what it is. Also, the entrances to the fields south of the DHL building still have the wartime concrete tracks which would have led to the dispersed sites. If you look at Google Earth these are very obvious, as are the outlines of the ablutions blocks near the old sewage plant.
I've just consulted Action Stations 2... not very useful, plus there's quite a few errors, at least for Wymeswold.
