if you drive is normally 20 hours add another 5 hours - traffic is going to be bad.....
Yes I know you drive at night - so it is not too bad - but I do too - there are a lot of folks that now drive at night - as I learned on my trip back from HH.
...when I post that we are 1 day away from leaving, I need you to promise that you will have the same aaarrrggghh feeling that I'm suffering from right now!!!
