So my son is too young to do much besides swing by some of our friends houses in his costume, but I know there are other little kids in our neighborhood so I figure I should be prepared. My wife and I both grew up in Minnesota and have only lived in apartments in Iowa until we bought our house in Des Moines this year. Every year I see things like "Beggar's Night" and "telling jokes" floated out on these boards and they are foreign concepts to me. Please give me a crash course.
