Let's be accurate. Northside Gym is at a Jr. High.
Yeah, it's on the campus of a middle school.
It was built in the 50s, at that location, because there was nowhere else to put it. They wanted a BIG gym. At the time, the biggest HS gym in the country with 8200 seats. New Castle bumped them from the top spot a few years later. It would still be #2, but they did some renovations and reduced the seating capacity to a measly 7400. You don't built that for 7th and 8th graders.
I'm not even sure Northside Middle School existed when the gym was built.
