RAF Binbrook.
Tim Mills,
Found a spot height of 124 ft near Binbrook airfield (seems as if it was at the top of "Ash Hill"). Yes, Geriaviator and his fellow juvenile delinquents did launch scrap bomb trollies down the hill to Binbrook village (the mind boggles !).
As you say, the rest of the county was flat as a pancake.
Cheers, Danny.
