Mr. Salyer,
Without entering into this debate, I do believe you are misunderstanding the "East Campus" and "West Campus" issue.
In the mid-90s, USD 383 built two new middle schools to alleviate the over-crowding at Manhattan Middle School. The freshman from MHS were then moved to the East Campus so that all grades would have more space.
Thus, East Campus is an all-freshman school. Freshman are bused up to the West Campus for varsity athletics, and both the East and West campus are considered "Manhattan High School."
Hope this clears things up.
