I can clarify = the cars were parked willy nilly before the snow started, then not moved for two days. Compacting the snow was not an issue. Fact is, 4 cars, parked in tandem, would about have covered the driveway, and as it faces south the sun would have melted most of it anyhow. All I can say is that is one messed up lawn.
And this morning, coming home from what I call work. Dude is in a 4WD truck. Doing about 10 mph under the limit. Ok, caution is good. Except it was in the 40s and there was no ice anywhere on any of the major roads. The route we were on had no bridges (why I take it), but regardless, had been plowed and sanded/salted/brined. Only some water was on the road. Ya never know when the dreaded black ice will suddenly form and attack your truck. In bright sunshine no less.
Yes, driving in the snow is an acquired skill. On my first trip to Alaska the California raised mortar guy slid right through his first stop sign. After that he got the idea to brake way before he thought he should and he was good to go.
Having been raised in New England, I sometimes forget that the Southern people have few experiences in snow. Or heavy rains. Or any inclement weather. Makes life interesting sometimes. And DW is from Idaho, she drives in snow just fine.
