I just received today (4/26/08) a toll violation notice from the Illinois Tollway Authority for 3 violations that occured while returning from the West Bend rally in July of 07. I thought that the reader just didn't get my EZ Pass transponder and that I would never hear about it again. I hope that I can clear this up. Illinois is in the EZ Pass interagency group so I should be ok. Has anyone else had any trouble with using their EZ Pass in Illinois?
