On the way down, we are taking I95. It is the shortest and fastest. However, on the way back, we are going around 4th of July so I am afraid of horrendous traffic (like we had last year). I was looking online and it looks like we can go through Greensboro, NC, up to Charlottesville, VA (and I know how to get home from there). Has anyone ever done this? Does it make any sense?
