Houston is synonymous with all things BIG. Appropriately, its economy is driven be an industrial base in energy, manufacturing, aeronautics and transportation. Hundreds of companies providing technology for the oil & gas industry are here largely in the Houston Energy Corridor. The city is also home to the Texas Medical Center, the world’s largest concentration of healthcare and research institutions. With its own incubator, the facility is well worth a visit if your interests are in the healthcare sector. Nicknamed the “Space City” (“Houston, we have a problem” – Apollo 13), Houston’s attractions also include an active Museum and Theater District, as well as the annual Houston Livestock Show and Rodeo, the largest annual livestock show and rodeo in the world.
