Assuming you use the 5 major sports leagues in the US, how many that you are a fan of reside in the same area? They don't have to be in the exact same city, for example the Celtics and the Patriots, or the A's and the 49ers, etc., but do reside in the same general area. Options depend on how many pro teams you root for, for example, I don't have an NHL or MLS team, but I'm 0 (Dodgers, Niners, Jazz).
