This post is very informative for me because my husband is going to have to drive to a class from orange county NY to Dulles airport in a couple of days. he'll be driving and going alone, I am nervous because it will be the first time we will be seperated. looks like its only a 5-6 hour drive but I have a horrible fear of bridges, tunnels and any interstate. I am so glad to have these tips and have been telling him all the you guys have posted. Thanks!!!
