Just ventured south up and over Bald Hill (~330ft ASL), relying partially on memory as its pitch black, in the densest fog of I’ve ever seen (no exaggeration). Immediate changeover at/after the summit to perfectly clear conditions. I’d only ever seen that happen on planes, not at ground level.
No lights on that stretch of road, everyone heading north will be plunged into instant darkness. I took a different way heading back.
Looks and feels more like Halloween than Christmas, especially with the full moon somewhat visible earlier when the fog was thinner, very haunted atmosphere out there.
