Flying site in Oshkosh?

[wwwarbird]

 I'll be passing through Oshkosh tomorrow (Thursday Sept. 2nd) on my way to Treetown. Are there any C/L flying sites near Wittman field and the EAA Museum that can be used? If so, where? I'll have some time in the late afternoon, so I was thinking I could get out for a few.
 
 Thanks!
