The depth of snow, as opposed to the coolth, could also be a major problem. Even as far west as JHQ the on-base MQs side-streets became sealed up every time snow clearance on the main roads was performed.
Then, once out [or into] the home straight, the deep frozen ruts decided where the car went, not the steering. Traction in rear-wheel drive was zilch, so I liberated a kerbstone and put it in the back of my big Vauxhall 2300 Estate.
Vodka in the windscreen washer tank of course.
A lot of people used bikes around the camp ......... although falling off in the ice and snow was common enough, we usually were cushioned by snow banks, even if dignity was bruised.
