No kidding those dorm rooms were (are) TINY!!! My first year I didn't have a roommate, which was rather nice. The second year I had a great roomie for the first quarter, and a heavy smoker the second quarter. She was a nice person, but I'm a severe asthmatic, so it wasn't the best match-up.
My sister went to UCLA for a while as well. She was in Dykstra Hall her freshman year (that would have been 1966), but she was a theater arts major, and I guess the competition in that program was just too much for her, so she transferred to Long Beach State. I still remember her introducing me to Lew Alcindor when I went to visit her ... I must have been about 14 then.
I pretty much lived over at the Bomb Shelter .... was that built when you were there?? It was in the Life Sciences quad, and I was a Chemistry major, so I was mostly either there or in the stacks of the Bio Med Library.
OK .... now I'm stuck in deep past mode.
