On my way to work today I saw a homebuilt plane fly too low and too fast over Black Earth, WI. Honestly at first I thought it was a large scale RC plane, even though it had lights. I was thinking, oh great, some joker is ruining our hobby... oh wait that's a full scale plane ruining a different hobby.
And on my way home from work (at 11pm) I saw a couple of planes headed north over Madison, WI. Those were going slow enough to definitely be piston powered planes. One appeared to be following the other, but not closely.
Point is, there is definitely more air traffic over Wisconsin.
I hope to go Thursday. I'm still mad at myself for missing last year but I was sick. Not way too sick to go, but just sick enough for it not to be worth it.
