I'll resurrect this thread to comment on the camera and the view of the salt.
I've started looking at it a half-dozen times a day - maybe more. I saw tire tracks the other day, for instance, and they show quite a bit of information about the condition of the salt. I'll assume that I'm not the only one, so I'm posting to tell the rest of you that haven't got in the habit - give it a try.
It sure isn't very dry yet. Check out how much salt fell from the vehicle (tire tracks lead me to believe that a vehicle was involved) while it was stopped.
