| The point of Rush is that you get to meet the frat/sororities for yourself. FSILG Rush is done after Dorm rush, and around the same time classes start (a little before they start FSILG starts actually). You don't have much else to be doing with your time during that time anyway.
Plus a LOT of people participate in the beginning of rush. Free awesome food (often lobster dinners, etc, that you normally can't afford on a student budget for a week straight!), you have to be crazy not to jump for it. |
