At least the fog is not very dense. We have been on the highway a few times already where the fog is so dense you can barely see well enough to stay on the road. Like you can not see anything at all past 25'. Scary as F*!
This morning was super frosty. Was -10 in Big Sky. I love the way the clouds and air looks when it is this cold, it’s as if all water vapor freezes and turns to a dusty snow.
