Yeah, it was kind of sad about the fate of the blueprints. The person who used them as such, who is also an engineer, absolutely detests the building. It's actually a grossly expensive failure of usable architecture in a lot of students' eyes, and, well, a lot of the people who have to use the building hate it. Hence, feeling vindictive enough to use the blueprints as drop cloth.

I know there is a least one other complete copy of the blueprints, somewhere. These just happened to be a copy.

That's really cool!
