Last Friday, there was a wall of darkness stretched across the interstate. The difference was night and day. I was driving in bright sunshine, and it was as if Saruman was perched on some hill nearby magicking a fey storm onto the road. I entered the roiling clouds and visibility was null. Snow roared everywhere--it was like some cosmic dandruff party. Then just as quickly as I entered the darkness of snow, I drove into bright sunshine again. The effect was uncanny.
