Airventure, ie Oshkosh has long be known for the honesty of people here, many cases have been reported of something left or lost, even something of value, and then being returned or turned in to lost and found.
I've felt secure here, for my plane and my things over the years.
I was sad to find out that not everyone is honest.
I did a forum yesterday, and when completed I was standng at the front of the stage talking to folks and turned to leave and found my bag that was on the table gone. It was only a yellow plastic bag, with a few personal papers in it, but the idea of such a thief still sits badly.
