4.
A once thriving industrial city in central Wisconsin that lost most of its industry (including Oshkosh B'gosh). It is now kept alive only by the EAA, Oshkosh Truck, and middle aged white people who work community jobs which pay just enough for food and taxes. The only diversity is a distinct Hmong population on the North side of the city, and is otherwise completely white. Oshkosh is sandwiched between two lakes with the fox river running through it, which gives it its never used nickname: Oshkosh on the water.
So I went to the EAA in Oshkosh the other week, I flew right in and camped under the wing of my plane! I love the EAA!

The EAA was here in Oshkosh the other week. there were pilots and tourists everywhere that didn't know where anything was! I hate the EAA!
