I have always wondered why the Nats were near the beginning of the flying season instead of the end? I grew up in the Cincinnati, Dayton, Columbus corridor and the weather there in the fall is really nice. I know there are valid arguments but I think the quality of the event would go up, especially in the qualifying rounds.
Just my opinion - Ken
It has traditionally been the middle of summer because school was out, so no impact to families or kids attending. Same with factories, etc, scheduled vacations in summer.
June is pretty rough, expect a lot of wind and bad weather, unlike mid-late July.
