Hopefully, the alumni leaders of those fraternities and sororities will display a bit of common sense about the need for members to take an expensive trip, hours away, in order to get drunk.Lots of fraternities and sororities and other college groups hold their annual events in Nashville as it is a very popular destination and they are heavily recruited to hold their events there. Riley was a member of the university chapter of the national fraternity and his chapter held their annual event in Nashville. Other chapters of the national fraternity from other universities may have also held their events in Nashville and perhaps they all get together at some point, but his fraternity brothers were all from the same chapter and university.
