good morning,fair comment and I will just add that 38 years ago we had no email ,internet or mobile phones.what happened locally stayed locally,but at that time local estates had a good relation ship with irad<institute for animal deases> and knew many of the people employed there.things move on,the irad changed its name to institute for animal health and security became a big issue and all went quiet but the pick ups still appeared every three years and the black rabbits arrived again so make of it as you will.these are my personal findings and memories, just a note for maximus number 1,the men initially claimed to be ferritting,2 I knew the men and where they worked,3 I was informed that black rabbits were used as can be seen at greater distances through binos etc
