For the last two months, some of your classmates have been taking part in the second incarnation of GoCrossCampus (think Risk + social networking + the 8 Ivies). Despite having far fewer players than most of the other schools, Columbia just defeated Brown at their campus, and is only one of three schools remaining. For those of you with burning hatreds of Penn or Princeton, or who just always wanted to march through Connecticut, this year’s version of the game will run until Monday.
