Remember...momentum is your friend. In the OLD days that was all there was....of course in the old daz there were lots of folks in the ditch too.
Load the rear end with as much weight as possible. Don't let air out because that will make the tires warm up and warm is not good when you are trying to get good traction. Skill level here is important...winter driving skills can make a difference as to whether you get there in one piece or have a white knuckle flight.
I remember the old daz... Dad was driving the Plymouth station wagon, we would go to school at a place we called " The Rock ", it was a private school, uniforms, nuns, any way to involved going up a big hill, The snow & ice would be so bad that Dad would wait at the bottom for cars to clear and then we would make our run at it.... LOL
Sometimes we would have to back down, and take another shot ! That was back in the late 60's early 70's with snow galore and studded snowtires and chains to boot.... I still remember Dad putting chains on the car. We normally only had 1 back in those days.... Sweet Memories... The Old man was all about traction, come to think of it ... He was pretty bad arse !
Kids nowadays are wimps.... Sometimes we would have to take the bus, ( Drivers name was Sarge ), they never cancelled school back then, If the bus wasn't going, my parents were still taking us to school... I can only remember 2 school snow days in all of 8 yrs, shat.... my kid ( son ) has had most of the last 2 weeks off due to snow days.... time for him to get to know the snowblower....
