The weather four months out of the year is disgusting (I live on the Westside of Los Angeles, and I would never consider living in the San Fernando Valley let alone the Valley of the Sun), and the nightlife is barely existent. I have been in Downtown Phoenix in November, right by Chase Field. Not a damn thing going on, and almost no one out walking the street. And the areas with bars either are for 50-year-old former-bros looking to cheat on their wives (Scottsdale), or college-age/recently graduated kids with the same Top 40 or country playing all the time (Tempe). Philadelphia has the exact same number of people and is a million times more fun and interesting. And much nicer buildings, too. Most man-made edifices in Phoenix are hideous.
God you're so full of shit. Nothing to do in Scottsdale or Tempe? Okay there bud.
