Me and my girlfriend, in our early 20's, are trying to plan a road trip at the end of july for about 7 days. We live in Buffalo, NY and would like to visit Washington, DC and New York City. We are trying to save money so I was wondering if there are any national parks on the drive from Buffalo > Washington or Washington > NYC or the ride home, NYC > Buffalo. We seldom travel, and this will be our first road trip ever, so any ideas I would really appreciate. Also, if there any any attractions in between these locations other then national parks please feel free to share... Thank You.
