I only have to worry about the occasional Black Bear in my woods that wanders out of the mountains down here to the foot hills. Besides that coons, groundhogs, possum, deer & wild turkeys are daily visitors, but those we like & feed in the winter when they're starving. And a few copper heads every now & then (we don't feed them). When I awaken in the morning and go out on my back balcony deck, it sometimes is like the animal preserve outside the AK hotel.
And yes, I have a no swimming sign posted for my fish ponds.
