A Plague of deer

Two fatal crashes on Norfolk roads in a few days due to deer?

I drove on these roads for twenty years and never saw a deer. Mind you, a friend of my brother has had two accidents with deer in the past few years on the road between Norwich and Cromer. He was travelling home late at night after shift work so I imagine that the time of day or night is a big factor.

I left ten years ago and I don't recall any stories of fatal crashes with deer when I was there. Are there more deer about now? You wouldn't think so with the reduction in habitat over the last 20-30 years.
