I love it when the weather allows me to wear a sweatshirt and shorts (so it's a good thing I picked up an IU sweatshirt). I love sleeping with the windows open and hearing the trains rumble across the bridge. I love the way the cold air hits your lungs in when you run. I love the way academia seems to hang in the air as you walk across campus. And there's just something about that bright blue September sky. Autumn seems to have arrived in Bloomington (at least for the rest of this week).
