Right or wrong, deer are a real nuisance in our small'ish town. I see them in our yard a couple times per day (I've seen as many as 8 at one time). My wife has a couple of flower beds and, despite constant spraying with deer repellent, sometimes we go out in the morning and a bed will be decimated. They are close to being domesticated. I can routinely get within 20 feet of one (or more) before they move away (even when they have young ones around). My 60 pound dog pays no attention to them any more as they are kind of like neighborhood fixtures. And they are not afraid of him either.
They can get pretty irritating. Fields and woods abound in the area. I'm guessing that they stick around because of all the gardens inside the town.
