Used to live at a place with a massive coyote population. We got em here, too, but nothing like that. Nightly they'd yip as they ran around our yard, dozens of them. Every single night. You'd sometimes see them like a whirlwind, literally circling the house and making the craziest loud group noise. It didn't last long, as there got to be more human activity at the house (it had been empty for a while, and then occupied by a lone meth head who never went outside) they found other grounds up in the woods. But for the first several weeks we were there it was terrifying to even consider going outside past dusk. If you left something in the car, you just had to wait til morning for it.
