The Chamber of Commerce began the processing of fruits and other products to offer a permanent display for visitors as proof of what the land could produce.
It was through the combined efforts of these businessmen and pioneer farmers that Congress was convinced to bring into effect the plan of Reclamation to capture and hold water from the Colorado River.
The hauling of crops to market, along with the rapidly growing change in transportation from horse-drawn vehicles to motor travel, created an insistent urge for a paved highway system.
The ease and comfort of traveling over paved highways brought more fine hotels, guest ranches on the city's outskirts, and an awakened consciousness to the possibilities of selling the climate to people who lived in less favorable parts of the country.
This, in turn, led to the development of the National Advertising Campaign, sponsored by the Chamber of Commerce and supported jointly by Maricopa County and the City of Phoenix.
