I was plowing a driveway last weekend, the residents came out to move 3 cars. One car had to be pushed, so one customer and I pushed it. While pushing, his keys must have fallen out of his pocket and landed in the snow. I continued plowing the driveway, and plowed the keys deep into a 6' high mound of packed snow at the end of the driveway. His car was stranded in the middle of the road, in a snowstorm.
Oh well...April is only 3 months away!
