As automobiles became more available to the common consumer, the advent of motoring vacations was begun. By taking in these constructed views, people had the opportunity to re-define themselves as Americans.
Americans have been defining themselves through their relationship to the land for a long time. Why does this re-connection to the land come about in the 1930s? Undoubtedly, the park and parkway movement was a reaction to the industrialization and urbanization that had been developing since the Gilded Age.
The design of the Parkway employed the principles of picturesque naturalism, which sought to elevate the mode of feeling of the traveling motorist. Part of this "elevation" was the understanding that these landscapes made up part of their national identity.
