I will tell you an area that it is more than possible,- myself and a mate were driving past the Killhope Lead mine (Alston road) towards Stanhope, at about 1.30 in the morning after doing some work for a friend. There was just a carpet of rabbits the further we got down the road, we had to slow down we were running so many over, it was dangerous to drive. I have never seen so many rabbits at one time. We had no dogs or guns with us. Anyone living in that area has it good.
