Hey everybody!

I'm new on the site and I hope to find a lot of tips and information! Last year August 2003 I made for the first time a road trip. L.A, Las Vegas, San Francisco with the national parks like the Grand Canyon. This year I wane make a road trip with the next following cities;

I have to start in Chicago.
then I wane go to Detroit, Niagara Falls, Boston, New York, Philadelphia, Washington D.C, Shenandoah Valley and at someway back to Chicago. I was thinking to drive from Washington D.C. to Cincinnati and Indianapolis to Chicago.

Is there anybody who made a road trip like this? Or does have anybody some advice how to plan a trip like this? I think that I choose too many cities for two weeks. Can anybody help me?

Regards George
