Just before George Bailey's life is upended in It's a Wonderful Life (one of my very favorite movies), he says, "You know what the three most exciting sounds in the world are?  Anchor chains, airplane motors, and train whistles." 

I have to agree...although I think I would add hot air balloon burners in there as well. 

I am ever so gradually inching closer to being able to enjoy all of these with a lot more frequency, and I. cannot. wait.
