The whole point being is, ONE SHOULD NEVER TAKE A MINOR ROAD IN WINTER where it has snow and sleek, at high altitude. It is just plain common sense.
To travel in the treacherous Pacific NW mountain roads in Winter, with a 4 year old and a 6 month old baby is downright stupid. I am sorry but this is a tragedy that can totally be avoidable with the slightest common sense.
