The event was originally started as Sibling's Day in 1999, but was such a success, it was expanded into an entire weekend in February 2000. The purpose of the weekend is for OSU students to spend some time relaxing with their brothers or sisters, organizers said. The event also gives brothers and sisters a chance to experience a college campus, and perhaps get them interested in attending college. Activities include dances, art workshops, sport activities, a hypnosis show, and other events.
Activities cover a range of ages, from elementary school to adult.
The event is sponsored by the OSU Memorial Union Program Council, a student-run group that plans and organizes campus activities.
