For what it's worth - even in our beloved South, all college campuses are not alike.
Within the same STATE you will find differences between campuses, and chapters of the same GLO. To cite an example with which I am familiar, no one will fail to miss that the campus climate and Greek system at the University of Texas - Austin and Texas A&M University are vastly different. Are there some similarities? Sure - you can find some cultural similarities. Most of the students are Texans, and there will be some aspects of being Texan that will be evident. But they are not the same.
There is a discernible difference in greek systems in the north, south, east and west. I think we all accept that.
But in terms of my sisters from other areas those differences are secondary to what we share. Were that not the case, there would be no sense in having an International organization that uses the same ritual. I've met sisters from all areas, and one of the things I cherish is the ability for what binds us together to overcome those geographical differences.I've met some great women who are totally different than I. I feel sorry for any member of a national/international GLO who wouldn't feel that bond with other members of the GLO.
