When I lived in Buffalo, NY, I always thought packed snow was the best to drive on. Know your limits. But all the lawyers and soccermoms demand dry pavement as soon as they hit the roads. Sooooo, salt a plenty!
I used to undercoat my pickup every fall with a gallon of chainsaw bar oil. Environmentally friendly and sticky/clingy. Smeared wheel bearing grease on all the brakelines/nuts/bolts on the underside. Worked well.
Really spoiled now in SC, ride yearround and NO RUST
