The postborder metropolis of Bajalta California stretches from Los Angeles in the north to Tijuana and Mexicali in the south. Immigrants from all over the globe flock to Southern California, while corporations are drawn to the low wage industry of the Mexican border towns, echoing developments in other rapid growth areas such as Phoenix, El Paso, and San Antonio. This incredibly diverse, transnational megacity is giving birth to new cultural and artistic forms as it rapidly evolves into something unique in the world. Postborder City is a genuinely interdisciplinary investigation of the hybrid culture on both sides of the increasingly fluid U. S.-Mexico border, spanning the disciplines of art and art history, urban planning, geography, Latina/o studies, and American studies.
