Hello,
I am from northern wisconsin but won't be able to make the Quilt Expo... it is on my 'to-do' list.
But an FYI - there is a quilt exhibit at the Milwaukee Art Museum that I plan on taking in when I am in the area in August. Here is the link

It is running through Aug 6. I think my girl friend and I will be going the next time I am in the area.
