The Old Pueblo, as Tucson is affectionately known, is built upon a deep Native American, Spanish, Mexican, and Old West foundation. Arizona's second-largest city is both a bustling center of business and a relaxed university and resort town. Metropolitan Tucson has more than 850,000 residents, including thousands of snowbirds who flee colder climes to enjoy the sun that shines on the city more than 340 days out of 365.
