People at my university used to live in the woods, in tents. Some were known to construct multi-storey treehouses. Says a lot about the institution I attended. (It says it was full of hippies, rather than that it was expensive.)
Can't you just live on campus and cook your own food rather than eating at the cafeteria? Or are you forced to pay for the cafeteria as part of the package? I'm unfamiliar with the american system.
>Where I went to school there were carefully camouflaged dugouts in a canyon behind the physics building where there were about a dozen students living incognito for free.
That sounds awesome. This probably isn't correct, but when you say camoflaged dugouts, I'm thinking of an elaborate system of WWI style trenches, or perhaps that Al Queada cave complex that Dick Cheney saw in a fever dream. In my mind, it's like some kind of survivalist-nerd version of a frat house.
I doubt I would have been able to resist the temptation to forget my classes and concentrate on expanding my invisible canyon-based physics fortress. Who amongst us can honestly say that it has never been their dream to inhabit a secret underground base with a team of renegades?
