Been a supporter of Arsenal since I was a teenager (they were pretty much responsible for putting soccer on my sports radar), and shortly thereafter Barcelona too (mostly because I love the city). However, TFC have definitely supplanted both as my main soccer obsession.

Hard to say exactly when it happened - several years ago at this point. You just feel an additional level of "ownership" over a sports team, when it's actually your home club, and not a team you follow from a thousand miles away.
