'Cause they be small. Oh, they're there. It's just kind of hard to see a mouse from yards away (even with glasses). On occasions, big animals (horses, deer, bears) will "visit" the burbs, but they prefer their privacy (rural areas where there's food and peace and quiet).
I live in a rural mountain area along with a lot of wildlife (bears, deer, mountain lions, raccoons, eagles, etc.). And I will say that I much prefer living with wildlife than I do living with people.
