2. Each campus is unique and that must be factored into what is done there and how it is done.
Unfortunately, you cannot simply take the model of the best college ministry you know and drop it onto another campus. Each campus has it's own schedule of which nights work best, the type of students who attend there and the over-all culture. The Princeton Baptist Campus Minister says 2 Night retreats don't work well there cause students don't want to be away from their studies that long. Some campuses students treat Friday classes as optional.
Listen to your students. Study your campus. Try things and then tweak them. Your ministry must be tailor made for your campus!
