GRHS' Student Council and the school facility served as the host of the 2010 Minnesota Student Council State Convention in April. The Theme was "Survivor Northwoods: Leadership By Nature"
Similar to other northern Minnesota high schools, GRHS has two homecomings: the traditional Fall Homecoming for American football and a winter homecoming for ice hockey. The school also has a "Spring Fling", similar to a homecoming week. All three events are usually a week long, with a different dress-up theme each day, with Friday being Orange & Black (the school colors) Day. Friday also commonly has a shortened class schedule with a pep fest in the morning.
