Weekly field trips to Westchester County and parks such as Van Cortlandt Park and Kykuit, the Rockefeller family estate, served as testing grounds for the women to try out their designs, trying to see if they could fool passerby or if their photographs showed they had succeeded in making people disappear from view. They eventually moved from clothing to painting dazzle camouflage on ambulances, ships and tanks. Units formed in various places throughout the United States, including Iowa, Minnesota, North and South Dakota, and Philadelphia.
