My opinions about EDC on campus are probably not altogether aligned with the mainstream of thinking, but then again I don't put my faith in the ability of any security group to protect me or mine from attacks or catastrophies beyond a very limited and mostly ineffective point. My recommendations are to keep on you what you think you will need to effect your escape from a potentially hostile or lethal enivronment, within reason, and to be wholly inconspicuous about what you carry. That said, there are a number of assumptions that can be made about the situation you are likely to find yourself. For the most part, you are not likely to need to evacuate the campus altogether, and wherever you end up, it is likely you will have food and a place to sleep, such is the nature of communal living. Orienteering and firemaking are not high priorities. A means of contact with the outside world might be a good idea (eg cell phone) so that loved ones can be assured you are okay, or so that in the event you are the first on the scene you can call in aid. You have a bike, which makes you mobile enough.

All that is left then, for the most part, are really comfort and security items.
