This isn't Celtic or anything, but the Great Wisconsin Cheese Fest is going on in Little Chute, WI June 2, 3 and 4. http://www.littlechutewi.org/calenda...heesefest.html

and in August 25 and 26 is the Kermis Dutch Festival. http://www.littlechutewi.org/calenda...ts/kermis.html

It all is a good time.
