I may be going to a wedding to Chantilly, VA soon and I would like to take my grandson to some of the sights in Washington. I paticularly want him to see some of the Smithsonian Museums. I am afraid i CANOT DRIVE UP THERE. i amfrome rural NC and I am afraid of the traffic. Once I get to Chantilly, is there any puplic transporttion that I could ride to Washington? Does anyone know how bad the traffice is around Chantily? I will be traveling from NC?
