Why do you think that Phoenix isn't counted among the "great" cities?
By population (according to Wikipedia), Phoenix is the 5th most populated city in the US. However, when major events tour the country (art exhibits, Broadway and off-Broadway shows, comedians, music tours, etc), Phoenix is rarely included in the list of cities that are short-listed. (Usually, Chicago, Boston, New York City and Los Angeles are on the list.)
What are your feelings as to why Phoenix (and other largely populated cities) aren’t visited by cultural events?
