Been doing it for 20 years in the winter time. I place the WSM right by the garage door opening(I mean right by the opening, couldn't close the door if I wanted to) with the exhaust vents facing the outside and leave the garage door open the entire cook. When the cook is finished I close all the vents and leave the garage door open until the temp and cooker is cold.
