Another good trick is to stand on a street corner with a map looking lost. After only two or three minutes, someone comes up to you and gives you directions. Sometimes, two or more people offer their help. Everyone suggests a different route because no one know how to get there or even when you are at the moment. But that's not the point. The point is to get to know the English,not to find the way. After all, you've got a map for that.
