The top level locality category is for general or informational sites concerning this community as a whole, not necessarily for sites located in the community. Ajo, Spanish for "garlic", has a population of about 4000 and is located in a remote area of southern Arizona (120 miles west of Tucson). The town's economy originally centered on a large mine that was open from 1926 to 1985, and now serves mostly as a retirement community and a waypoint for tourists heading from Phoenix to Mexico's port city of Puerto Penasco. Ajo is a thriving community during the winter months, but during the scorching summer months tends to be a quiet place. Small, with no neighboring communities and a weak economy, Ajo has escaped the tentacles of retail giants.
