Damn, black ice scares the shit out of me. Stay safe dudes...
Definitely no joke. When I hear the words "freezing rain" or, "ice storm", I'm either calling off or, finding a way to come into work early. Only time I had to call off this year was back in Feb. when we got 6 inches of snow right before I went into work.
Normally, I drive 60+mph the whole way to work but, on nights where it snows, I've been known to back them up for miles driving 20-30. LOL.
