If like My Alma Mater, darn little.

Well, actually nothing, it is left up to each Fraternity. OKAY, so be it!
LX Z, PSU, Kansas does a Western Week. That was something that We did to combat SX so to speak and their Derby Days.
This year, the Zeta is planning on having a Watermelon Bust one day during the week along with a Poker Tourney and other things.
Last year, We had a Sea Food Cook out for Alums to come back to for the weekend. It was great.
Why wait for IFC to do something when you can PR the heck out of LXA doing something instead?
Volley Ball, Dart, Horse Shoe, Pool tournies for example to get interation with other Fraternitys?
We do a yearly Hot-Tub-A-Thon with a Sorority for Charity when the weather is cold so the steam comes off of the tub for PR relations. Ergo, both get names in lime light!!!!
