Yeah, mountain driving...
A family friend was working year round at Yosemite. Four or 5 days before Christmas a blizzard moved in and parked. No one up or down the mtn, phone lines down etc. I used to hike Yosemite every winter for photography so I knew the area pretty well. Knowing that, her parents kept calling to ask if I would go get their daughter in time for Christmas. I kept saying the roads were closed, I'm sure she's safe, yada yada.
I finally caved on Christmas Eve. It was a four hour drive to the foothills and then up into no man's land. It was an adventure. I packed my 4 season bag, clothes for a week (tons of socks) and a large suitcase of food. No pax. Problem was the main road was already closed so I had to go several hours out of my way to take a secondary road up the mtn.
It was awesome! It never really became daylight because of the heavy storm but I didn't get to the mtn until after dark. I knew I was the only vehicle on the road but saw signs of a snow plow way ahead of me. Twisting and turning up the road, bouncing off snow banks, I finally caught the snow plow. He was having trouble getting through himself. We got to a turnout and I jumped out with a thermos of hot coffee as we discussed my plans. He radioed to another plow on the other side and he came back saying it looked like the storm was breaking for a bit.
The plow I was following had to turn back so I was on my own. I was in 4 wheel drive with chains on all four and even still was just on the edge of getting stuck in some places. One snow bank I hit partially collapse on top of me. Speed was my friend as I powered out. Try speed shifting wearing Sorrels.
The combination of the night, the trees and the white-on-white made it seem like I was driving in a dimensionless tunnel. I lost track of time as everything became surreal and a blur in my mind. My only focus was trying to remember the lay of the road. I knew the road and knew my location but danged if I almost didn't lose the road many times. I was also getting sleepy. Merle, Waylon, and Hank Jr blasting kept me going.
I was at the point of telling myself I should stop and wait for morning (yeah, like that's a good idea) when I started to pick up signs of another vehicle. It could only be the other plow. Sure 'nuf, I caught up to it not too much later and he took me down into the village.
I knock on my friend's door and she almost drops to the floor seeing me. She had no idea I was coming and she had already started into her depression of spending Christmas alone with little food. She was part of a skeleton crew, the rest had gone down the mtn the week before.
The kicker was the snow plow guy said they don't usually plow that road in winter. Oh yeah, when they close the road there is also a large metal gate (painted white!) they place across the road at my destination. If it had been shut I would have probably wrapped myself around that gate. Then he said if you wait a couple hours they should have the main road open. We did and they did. We slipped and slid down the mtn and on to her parent's home. We got there just before dawn.
Then there was the time I parked my white car while I went for a short day hike for some scenic shots. When I came back only a couple hours later I couldn't find my knee deep footprints or the car. But I did find bear tracks criss crossing my trail....
(not all bears hibernate)
I've done that way too many times - usually in the mountains. Not fun. 
Your following a plow!
This morning it was -31 and wind chill around -50 or something.
