I've got +/- 2 inches of solid ice on the driveway. Put 200 pounds of salt on it earlier and it is just laughing at me. Driveway is about 1/4 mile long and only really worrying on the inclines - we are about 60 feet below the road.
I teach salt application trainings for public works and well in this circumstance everything I preach will go out the window because I could not get out to the road right now if I had to.
