Of course for winter driving in the north, you NEVER go out on the interstate without survival gear...EVER! Always keep the vehicle stocked with enough blankets, sub zero sleeping bags food, water, heating elements etc to keep all occupants warm for a few DAYS. When storms hit the interstates can get jammed up bad , sometimes for a few days and you can very easily find yourself stranded with aq few hundred other motorists out there with snow over your roof for a few days waiting for the plows to come through and even then you might not be able to find a place to get off the road, by then all the motels and restaurants may be all parked in and you may have to keep going. Never let your tanks get below half in northern winter driving. You never know what is going to happen next. A little preperation makes the difference between a minor inconvenience and a major story on the national news
