or perhaps it is a group of ISU students that are NU fans? my friend's husband went to ISU, but was from Lincoln--not that he would do anything remotely close to this, but stilll.I haven't been on campus since Wednesday - are people trying to clean them up? Does it seem odd that they're there during the school week? I would think NU students have class today?
it's just chalk, right? water should do the trick.
