Plus, no summer day is brighter than a clear winter day with snow on the ground.

It is if you live in a part of the world that is dark for months at a time during the winter, like reindeer do.

Most reindeer live North of the Arctic Circle, where the sun does not rise above the horizon in winter months. I suspect most summer days are brighter than the few hours of twilight the reideer get in December.
