That's nothing, you haven't seen a thing until you get behind a yellow PennDOT plow truck. There is an even coating of loose rock salt covering my street right now, I kid you not. You could literally shovel it up off the road.
Same thing next door in NJ, I read a study that a lot of DOT not only dump more salt than is needed, they dump more than they even should and are poisoning the soil. That is besides causing undue car rot and pavement decay. There must be a shady kickback going on.
Just now, the local news said we been below freezing for 103 hours.
