Since when do country clubs rent out their premises to overwhelming amounts of middle schoolers? What would the transportation be? 400 parents all stopping their lives to drop off kids, maybe a bike valet? Who supervises all of these kids? What DJ actually wastes their time and resources to set up sound systems and play for a bunch of middle schoolers. How was all of this funded?
This whole thing sounds absolutely ridiculous and I simply can't believe anything like this existed.
But if it did exist a party with 400 middle schoolers sounds absolutely horrendous and they should have shipped the whole country club to a deserted island.
