When you lived at Towers and had a 2 hour break between classes and found one of those big comfy chairs on the second level of the library available in wintertime with the sun shining through the glass and you just curl up like a cat for a decent nap. The Terrace Room at the Union (can't remember what it was called--the one that had the piano in it) overlooking the fountain was a good place to try and get a nap as well, but much noisier.
The old Trophy Tavern was a smoker's lounge and full of vending machines with anything to get you through the day. I have the large portrait of Cy leaning on the MU that was centered on the west wall with smaller portraits of the other Big 8 mascots on either side. When the Union was renovated in 95 I discovered it in the dumpster and asked if I could have it. One of my most prized possessions.
