Never had a deep snow fight , had one with a dusting on the ground, but it isn't much different then a fight without snow, other than the the temps, and footing , once the fifth starts your steps and hers will pound the snow flat and into almost hard surface and as you both roll on the ground flattens it as well, one thing i am sure we all can attest to , once jackets are off and you fight you don't feel the freezing temps with your adrenalin pumping, but faces and hands turn bright pink
