This is the back of the Nu Delta house.  The roof access is interesting.  I can't remember what the access was in the early 1960s, but it did exist.  Since I'm acrophobic, I only took advantage of it once.

Five of the windows have air conditioning units.  I'm pretty sure we didn't have anything like that back in the 1960s.

Taking this photograph in mid-summer, when the house was likely to be sparsely occupied, if at all, was a little unfair, but it was when we were in Massachusetts.

This picture, from the 1966 rush pamphlet, gives a glimpse of some of the back of 460 Beacon, 50 years earlier (no a/c).
