To anyone who cares and perhaps has been watching my travels: this morning I arrived at the big airshow in Oshkosh, Wisconsin. Details of that airshow may be found at http://www.airventure.org/ and at http://www.airventure.org/live/.
This is believed to be the world's largest airshow. For one week every year, the small airport in rural Wisconsin has the world's busiest control tower. I brought an aircraft walkie-talkie and have been listening to the tower frequencies. They are busier than New York City's airports.
This place is a zoo! Tens of thousands of motor homes, camping trailers, tents and pup tents, are stretched out as far as the eye can see, along with hundreds of airplanes of all sort: antiques, military, homebuilt, ultralights, trikes, powered parachutes, helicopters, and more. Almost anything that can get into the air is here. I'll post a few pictures later.
