Am remembering some years back when I lived at the bottom of a steep 1000-ft blacktop-paved driveway and what it was like to get through winters with that thing... If the plow truck came before you got out, you were (ironically) pretty much stranded, because the thin layer of whatever it left behind would freeze into an ice ramp. Any attempt to leave would ultimately result in a sideways back-slide and getting stuck diagonally in the driveway. Once, the tow truck that came on a rescue mission ALSO slid & got stuck...thankfully only temporarily, but it raised a few heartbeats. I've got a healthy respect for the challenges of hill-living.
