It is extremely foggy tonight. The weather service says visibility is 0.0 miles at the airport right now.
Driving in fog so dense is difficult; you can't tell what you're going to do until you're doing it. It's either fun or terrifying, depending whether you like the sensation of hurtling forward into nothingness. I happen to feel both ways, so I alternated between shrill giggles and tiny whimpers as I picked my way along the freeway ramps on the way home from the store.
