Man, I could compile a list of dirty, filthy buildings on the UM campus in the mid-80s. My freshman year, I worked for the UM Housing Office, and we had a lift truck that we used to deliver and/or switch out furniture, refrigerators, stoves, etc. in the Apartments area (none of those 3-story buildings had elevators).
I was shocked at how squalid the "married student housing" was, both along ****inson Drive and across US-1. I was somewhat relieved when UM decided to get rid of that housing. I mean, it was tough for students who had young kids, but UM should have never allowed young kids to be raised in those sub-standard buildings. UM was like a slumlord in those days.
The basement of Mahoney-Pearson. The backsides of the Student Union (both by the Stanford Circle and the Miller Circle). The Ibis and the Eye and the Hurricane cafeterias. The art shacks. The OLD Lambda Chi house. The OLD Sig Ep house. The Army Armory building. The ramshackle Law School quadrangle, pre-renovation. The Ungar Building. THE ENGINEERING SCHOOL (particularly the nasty basement/ground floor). The Learning Center, complete with their anonymous NYSOM-friendly restrooms.
And, of course, the granddaddy of them all, the Hecht Athletic Center.
