Welcome to Naptown. Don't expect Chicago or Philly; but it's far from Mayberry!
The scene is "laid back" here- IMO, it's the best place to raise a family (for cities/metros larger than 1 milliion people). If you search, you can find/do just about anything here. What are you in to? I can recommend some spots.
You are just in time for the Indiana Black Expo and Coca-Cola Circle City Classic. If you have experienced it recently, you should. It's an eye opener.
