If possible you should take your time traveling from New York City to Washington. Using local roads instead of highways saves toll fees, doesn’t take that much longer, and offers you some insights into smaller towns and villages.
You will cross five states: New York, New Jersey, Philadelphia, Delaware, and the District of Columbia. And remember, this is the United States. So, expect to see many weird signs, people, buildings, cars.
