To add to what Glitter650 mentioned, we had a "no balloon" rule in the past because of the room we used to have Open House in. The building manager was afraid they would get loose and be stuck in the room forever (it was basically an auditorium which had really high ceilings).
I was really surprised this past weekend at my Regional Conference hearing how different recruitment is among Alpha Phi chapters. There was one chapter that had a rush budget of $15,000!
Then there were chapters who had a very strict "no frills" recruitment. At one campus, they lined the girls up and they were fined if their outfits were too similar!
That's just amazing to me.
