Hey, does anyone know to what extent we could "mingle" with OTHER colleges? I mean, could we freely walk around the grounds of other colleges (for my interview at my other college, at least, I could walk around freely but places like Christ Church, where to my understanding there is a fee for tourists, is it free for students of other colleges to roam?). And also, are we allowed to eat at other colleges (say for convenience if your college is on the other side of the town and you don't want to eat fast food or something XD) without necessarily having someone from the college accompanying you? I know that dinners are formal so you'd need an invitation but most colleges have a pay-as-you-eat for lunch I think so what about them?
