The Zeta Sigma chapter is really proud of the COB events we have planned this semester.
First of all, we're planning a movie night, and we also plan trips to the Mall of America (which has an amusement park - yay!), but, we're also stepping out of the box a little and having one where a black belt comes in and teaches us some self-defense moves and at the end we'll get our "pink belt", as well as golf lessons/business etiquette night, a Cookie Factory tour, etc.
Most of our COB is informal, though - asking new girls to lunch with us, going to campus events (Dave Coulier from Full House is going to be on our campus tonight!), or just hanging out at our apartments.
