One of the highlights of my education was finding creative ways to cross the campus. There is an extensive network of above and under-ground walkways through and between various buildings. Some official, and some less official (but still functional!). By the time I graduated, I could get from one end of the campus to another with barely any exposure to the weather, if I so desired. I delighted in building my own secret map of high-ways and byways for myself and some close acquaintances.
