I was in Oshkosh last weekend, talked to the guy that owns the house we rent for the week of air adventure.
He informed me that this year air Adventure and Rock America happen on the same weekend ( the friday and sat before air adventure starts on monday)
the house is between the north 40 and Pioneer airport--even though Rock America is on the other side of the highway, it sounds like its in his back yard!!!!
Lasts until very late at night---So if you come to Oshkosh early that week---BRING YOUR EAR PLUGS--if you want to get any sleep
