My driveway is probably 150 to 200 meters long and is a steep slope upward. I busted my a$$ to keep it clean over the past few weeks so I could get the Boxster in and out. If the snow sits on the driveway and get packed down by tires then it turns to ice and even the Boxster with snow tires cannot make it up. Hopefully most of the snow has fallen already for this season.
