Yeah, usually they make a good amount of money during that week and love it. I know wait staff that make more tips in one day during AirVenture than an entire weeks pay and tips any other time of the year.
Trust me. A lot of people here hate it. Every year we go through the same thing with people saying it needs to move away from Oshkosh. No matter how much you try to explain to them how much money it brings into the city and local area they don't care and just rant on and on about it. You may not see these people because they don't go on the south side during that time as much as possible.
My father-in-law is one of those people who hates it with a passion. Last year we invited my wife's uncle (her dad's brother) out to the hangar to watch the Thunderbirds. Like a good big brother he called my father-in-law just to blast him with jet noise through the phone
I'm not going to argue with people on here about it. I grew up and lived/worked in Oshkosh my entire life and I will tell you there are a lot of people here who HATE Airventure and wish it would go away. Every year I try to tell them about the benefits of having it here but they refuse to listen to anything. Owning a locksmith business I make a lot of money that week myself, but I also drive everywhere around town and the traffic is nothing compared to driving in Milwaukee or Chicago, not even close (EAA, Oshkosh PD and Winnebago Sheriffs Office do an amazing job keeping that amount of traffic flowing)
I do agree that wait times are a lot longer at resturants that week, but so what. My only gripe is all the out of town drivers making my daily drive a real adventure as they drive through the roundabouts like madmen... (Don't get the locals, mainly those over age 55, started on the roundabouts. You will get an earful).
