It seems reasonable to start a thread about this. Please feel free to post any pertinent information. For starters, see the main page of NUFORC - The National UFO Reporting Center. http://www.nuforc.org/ This is the report database for Illinois. See November 7th, 2006. http://www.nuforc.org/webreports/ndxlIL.html Also http://cosmiclog.msnbc.msn.com/archive/2007/01/02/25212.aspx [Broken] If you check post 78 of the UFO News thread, you will see that there have been three other UFO events involving multiple witnesses around the Chicago area in the last two years.
