Two of my ex-roommates are in Scotch Guard which is exactly like Angel Flight,but is for Army ROTC. Both orgs are very good. Both are very active in communiy service. Scotch Guard has a website in student organzations page on the LSU home page.
Angel Fight is huge at LSU to. In fact, a couple of years ago, 2 guys joined. I think the first guys ever to. The LSU unit is also the largest chapter in the country. When I was in, I think there were like 90 activies. To say it rivaled a sorority would be an unstatement.
Carnation: LSU's chaper is Frank Haggan I think. It's been awhile so my memory is fuzzy at the moment. I thought I had my pledge manual with me that had all the information,but I must have left it at my mom's house in New Orleans
