A large high school in Carol Stream, Illinois, part of the Glenbard 87 School District. Often referred to as a prison because it has no windows, and must be heated with bunsen burners because the school is at a constant 56 degress. Hallways are color-coded so that you don't get lost at there is no outside point of reference (see above). Glenbard North (often referred to as GBN) is the loner school in the district, hated by East, South, and West, because it is so far away from them. Sometimes confused with Glenbrook North (especially after the hazing incident) and known for getting into a brawl with Fremd High School during the football playoffs in 2007. Their mascot is the panther, and wrestling is a frickin cult.
