My son works for VDOT and when the roads get icy, etc. they are out in 12 hour shifts. He is head of the night shift, 8pm to 8 am and I worry alot. He takes alot of the roads that the other guys are scared of because he once told them, mom taught me to drive in the snow and ice, so I know what to be scared of....There are a couple that I don't think that I would tackle and I do worry...but I understand that there are times that you have to do it. They have had a couple of guys do some "ditch cleaning" when the roads are icy and there is only so much you can do to stop one on ice...they will back up or down a hill sometimes to get the grit on the roadway for traction...
