I am distressed that some of the animals escape and end up on the A5.
On Sunday a doe was on the verge near Hockliffe,.and I have seen a dead Deer lay by the roadside which I had to move out of the way of the cars.
It is distressing for the drivers and the animals . I tried to contact the park but it was closed so I had to phone the police ,who were brilliant.
