Known simply as "the Valley" to local residents, this region demarks one of the southernmost points of the U.S. as the country tapers out between the Rio Grande and the Gulf of Mexico. With its mild climate and rich alluvial soils, this is one of the most productive citrus-fruit and vegetable growing zones in the state. Located along the coastal flyway, it is also an important stopover for migratory bird species as well as monarch butterflies in preserves such as Laguna Atacosa National Wildlife Refuge-not to mention the decidedly more rowdy species of lesser-winged spring-breaker at South Padre Island.
