"Bubba, I beg to differ. It is one thing to drive an older vehicle around an area that you know and, IMHO, quite another to start off on that many hundreds of miles by yourself with a child. Not that it cannot be done, but the odds of problems somewhere along the way are pretty high, among weather and potential breakdowns. "
I just have to opine. Sorry in advance! But are we such a society that we need a nanny (professional driver) to usher us down a freeway in the winter?
Any person with an IQ above that of a turnip can watch/listen to newscasts for snow information. A freeway is not a vast wasteland. There are cities (refuge and assistance) all along the route.
If forecasts indicate high snowfalls, stay put. Snow storms rarely (NEVER) sneak in and dump 10 inches between one town and another anywhere in the country. Rarely are freeways impassible for more than a day.
How in the world did the pioneers ever survive?
