The Repellent Fence is a social collaborative project among individuals, communities, institutional organizations, publics, and sovereigns that culminate with the establishment of a large-scale temporary monument located near Douglas, Arizona and Agua Prieta, Sonora. This 2 mile long ephemeral land-art installation is comprised of 26 tethered balloons, that are each 10 feet in diameter, and float 100 feet above the desert landscape.
