Delaware was the first state to ratify the US Constitution. Delaware is well known as a corporate tax haven due to its laxed and secure banking laws. It is bordered by the states of Maryland, Pennsylvania, and New Jersey. Despite being only a hundred miles long and less than fifty miles across at its widest point, Delaware is a surprisingly complex and diverse state. The C&D Canal, which bisects the state two-thirds of the way up, serves as a sort of internal Mason-Dixon Line, separating the more urban and industrialized northern portion of Delaware from the more rural "slower, lower" southern part.
