The roof top's checkerboard tiles were great for playing giant games of chess and for square dancing. Unfortunately, the evil forces of the B.B.A.C. (Back Bay Architectural Commission) decided that we shouldn't be allowed to have such a cool looking roof anymore and made us rearrange the tiles in a more conservative pattern.
The roof is still a nice place to hang out, especially during the summer. As you can see, we have a good view of MIT (the good part is that it's so far away).
The only way to go from here is down to the roofdeck.
