just to add one other note: Apparently, Depauw's first snow this year was back on around the second of December.
I dug up this tantalizing little titbit from twitter, posted that day by a student:
"So many people running naked outside of my dorm right now... This is why i love depauw!!!!

"
"First snow"? We already have a "first rain", so why not a "first snow"?
