6. See If "Use It" Is In Your City
"Use It" is an amazing map made by locals for tourists, and right now they span a little over 40 cities. You can see if your city has one by popping over to their website, and if they do the map will be a total game-changer for you. 

Locals map out do-it-yourself walking tours on the maps, telling you exactly what streets to walk down and what sights to see. Then there are over 100 suggestions on where to eat, where to drink, fun cafes to visit, quirky shops to pop into, and off-the-beaten-path sights to see. You'll basically get to experience the town like a local, and it will push you to walk into neighborhoods that you most probably don't get a chance to.
