A treehouse would be great, though. People could go sit on it to make out in the moonlight, have deep conversations on it, or just climb on it for fun. It could become a tradition in and of itself, meaning something different to each of thousands of students. It'd have to be constructed well, of course, and look good—none of these bright, primary-colored plastics for us sophisticated college students, as this will be a treehouse, after all, not a playground. But yeah...what a boon it would be to have such a thing.
Eh. Before that, though, someone just needs to get out of one of the existing hammocks downstairs so I can go lie there and read.
