Notre Dame doesn't have any social GLOs. They do have a very close residence hall system though. You live in the same dorm all four years and do things with your dorm-mates similar to sorority/fraternity events - service projects, mixers, intramurals, etc.
Yeah, i asked the same things when i joined my fraternity...the answer is no . Too bad too...i was hoping there was a teke chapter there, since it's only like 20 mins from my hometown. Stupid parents have 4 tickets to the USC game...40 yrd line like 10 rows up...and won't take me.
