Description & Facts: Oshkosh is in east-central Wisconsin on the shores of Lake Winnebago. Its unusual name has travelled far as the name of "Oshkosh b'gosh" clothing, and as a synonym for EAA Airventure, one of the world's great celebrations of aviation, held at the Wittman Regional Airport here. Oshkosh does not have any commercial air service, but Wittman Regional Airport (KOSH) can support any private aircraft that wish to land. If you plan to fly in here during Airventure, you will find yourself among tens of thousands of other aircraft doing the same thing. You absolutely must get the Airventure NOTAM from the Airventure website and follow it carefully. Regional commercial air service is available in Appleton (ATW) which is 20 minutes north. In some cases it may be worthwhile to use Milwaukee (MKE), 90 minutes south, or Green Bay (GRB), an hour to the north, and come the rest of the way by road.
