If any of these apply to you, then this article series is for you. Every week I will break the Route down into bite size portions that are equal to a day trip, that is of course based upon how close you are to the starting point of that article.
By my estimates a "day-trip" suggestion should take you about half a day to drive. I do however, take into account that with a family you will have plenty of stops, both planned and unplanned. This also gives you time to linger at various attractions along the way and still make it to the end point.
Look for these articles, I will be posting number 1 in the next few weeks.
