I should probably know this but it has been years since I have been to the WI State Fair.  It is just so far away, the MN fair is closer (and better 

 ).  But I think the WI fair is in July.  Fun fact: my 4H group performed twice at the WI State Fair.  Our group won many awards for singing, and those were the only times I was at the WI fair.   Actually the first time we were invited to go I was in 4th grade and I was super pumped to go.  Then crashing disappointment because I found out that it wasn't the fair I had been going to every year (which was the MN fair).
