This sprawling convention center provides great symbolism of the sprawling city that contains it. Expanded to more than 870,000 square feet (triple its original size) in recent years, this center attracts hundreds of business meetings and expos every year although some are not open to the general public. The diverse array of topics featured by these shows often brings in tens of thousands of people daily. Two 155-foot pavilions constructed of glass and steel highlight the recent expansion.
