Soooo pumped to see this thread! I love this show and have watched each season. This and American Idol are the only two shows I make time to watch during the school year.
I haven't really picked a favorite, but I really like the Air Traffic Controllers whose names I'm forgetting right now (I'm bad with names, forgive me). They've have their share of luck so far and I have a feeling they'll be gone soon

I think after them I like the two guy best friend team or the father son team. It's too early to decide.
I hope the show will still be on once I turn 21 b/c I want to be on it! How awesome would it be to travel like that!
