I remember driving to work on a foggy morning. I was on a dirt road, and I knew I was between point A and B, but not sure where. I was creeping along at 10-15 mph, and at that moment, I had a deep appreciation for the reflective marking on paved roads.
I'm not sure it was the same morning, but I was on paved roads, going about 30, thinking, "Hey old lady, can you pick it up a little?" Right then, I saw two horses walking up the road toward me, lost in the fog. I slowed down to about 20 for the rest of the trip through the fog.
