Kangaroos in the wild

It was incredible to come upon a mob of kangaroos in a clearing. They didn't seem bothered by us. On Kangaroo Island, they don't have many predators except for humans driving at night, so they've really proliferated. We had to drive quite slowly to make sure we didn't collide with the families of kangaroos trying to cross the road. They even have a "kangaroo crossing" sign!
