I have heard the big parade in Bologna, the Par Tot Parata, will be Saturday June 18. I have not heard what time it will start. From the videos of youtube, it looks wild!
Found two dates, 17th and 18th but no specific times. this does look like a good time. ifI get any better info I'll let you know.
Actually I just received a Facebook post with all the details. It's gonna be a real wingding! The big party the night before, on Friday. The parade & music from16:00-23:00 on Saturday. In 2009 30,000 people attended.
So I guess I answered my own question. http://www.facebook.com/event.php?eid=215236538496820.
