Planning a road trip can be a bit intimidating. As we calculate out our traveling time for each day, this trip is going to be quiet a long one. Mapquest estimated 1 day and 8 hours if we drive non-stop from Boston to Austin. Here is our route. Four days seems more reasonable to me.
Day 1: Boston to DC
Day 2: DC to Nashville
Day 3: Nashville to Little Rock
Day 4: Little Rock to Austin
