HI Mr_ mcrib .
Black ice is the norm. around these parts in Jan & Feb.,, when the temps drop ''sub zero'' ,,& the winds are blowing ect.
I hate those winter months here.
Here is a pic. from 2 winters ago,,
The Guy's up in WI. got it worse.
Am originally from the Bay area, & after the state getting all burned up,, it would break my heart to go back...
