There is a road and a petrol station behind that mound at Cambridge. One of the urban legend stories was that the mound had quite a few rabbits living in it.
When Marshalls first got a contract for converting Tristars from airline to military use (tankers?) back in the 1980s they had to perform engine runs. They duly backed the Tristar into the bay in front of the mound and fired up the engine(s). As they throttled up they blew the rabbits over the road into the petrol station!!
