Green Bay’s Titletown District will kick off the summer season June 2nd with an event called the Summer Fun Days Showcase.  Free activities will include a zip-line, face painting, Zumba, henna tattoos and more.  Organizers promise live music starting at noon, wrapping up with the Wisconsin-based BoDeans at 7:30 P-M.  Guests won’t be allowed to bring in food or drinks, but there will be plenty for sale.  Parking will be free in the Titletown lot on Lombardi Avenue, with more slots available at Lambeau Field.
