He said later he felt a bump and opened his eyes to a small cloud of snow in front of him, snow he had knocked into the air. Then he saw trees rushing at him and thought, "Uh oh. This isn't going to end well."
So on he plows, into the snow at the side of the road. And then the truck came to a stop. He said he sorta just sat there, with a white-knuckle death grip on the steering wheel for about two minutes. Then he began to realize his hands were beginning to get sore. So he let go. Then he just sat there a few minutes, taking stock and deciding he wasn't hurt.
Then he called his mother. That made her feel good, not that he was in a tight spot, but that he called her first. It took some doing and several other phone calls but they finally got the truck out of the snow and back on the road. He ended up getting towed back to a heated shop because the serpentine belt had been shredded and was all wrapped around a bunch of other stuff on and around the engine. That plus the engine compartment, in addition to the engine, was now all stuffed with snow. So they towed it to a heated shop, dug the belt out and replaced it and then left the truck there a while so the now could melt out. Then he came home and slept for several hours.
As his big sister said, "God loves you, Himbeere. He took good care of you this morning!" Amen to that.
