Crazy Tractor Driver Won't Say Yes

The sandbox top is Bailey's newest tractor obstacle. He's crazy! This video also shows how Bailey tell us yes. He nods his head and blinks his eyes. When we tell him to use words, he just moves his mouth. Besides NOT saying yes, Bailey's vocabulary is increasing everyone. He says the colors, please, juice, up, down, on, off, Bubba and repeats other words that we say.
