Each thank you note is both missing a word and also references a location on campus where there is a class gift (whether this location is described at the beginning or the end of the note is indicated by where the exclamation points are). The first letters of the missing words in order spell the first part of a clue phrase
HER NAME IS. When the missing word is reinserted into the note, all the notes have the same number of letters and numbers (150). This is the same as the number of graduating classes there have been at MIT since the first graduating class of 1868. Indexing into the note by the graduating class number spells out
ALL GIVING when ordered by graduating year. The overall clue is
HER NAME IS ALL GIVING, cluing
Completed notes follow:
Awesome! I was outside seated on a bench (two trash containers before me). To my left, I see a brick non-building wall. Over a plant, the right sign’s dedicated fondly to a husband who is loving.
I go past a wavy, multicolored bench, went down the stairs by the eleventh president sign, turned around and went back up and went left. There’s a great place to find red places to sit! Neato!
I go past this plaque on my left indicating it was reconstructed in 1988–1990 and after crossing the street, looked left and saw an amazing description of a unit. Thanks so much for this!
I sat on a couch underneath a head, MIT Newspapers Only sign in front of me. I had to go outside, so I went up the stairs past the doors. I turned, looked up and discovered I wasn’t late after all!
I start by entering the basement and I pass the Amnesty International office. Down the hall in the sitting area, I see a way I can use both of my thumbs to make streams of water appear! Whee!
I think this place is awesome! I was sitting on a bench here outside watching the water just barely cover the rocks. Beyond it, there’s the bridge from Alexandria in Minnesota going over.
I was exiting a place for getting in. Directly across, I spot a sign listing at the bottom three things that were negative exposed. I turn right and on my left I see a lot of names on the wall!
I was looking at a room from above. I go down the stairs that turn left partway down. I go left. I see a glass sign mentioning a larger institute program in front of a sleeping place for some!
I was very lost by a No Storage Allowed sign. I go outside after going around a pillar and up a ramp (elevator signs pointing where I came from). Now, I have to cross the street; I know where I am!
