I helped Glenn pull the Canuck and the Dh-4 out Saturday morning so he could run their engines to get the radiators warm and coated on the inside with the coolant. I got to sit in the Canuck and listen to its engine idle. Then we put a big trash can underneath them and emptied the radiators of their coolant to store the airplanes for winter.
