I just received, you guessed it, a “Notice of Violation” for travelling 67 in a 55 on 5/30/2014. I was travelling from South Dakota to Chicago. Usually I take I90 but there is some construction I was trying to avoid in Illinois around the Rockford area and into Chicago. I’d love to go back to Cedar Rapids and look at this stretch of road and understand where signs are posted etc. Also, how can everyone seem to get the same speed issued? Sounds to me that there is a problem with their radar or laser gun they are using. Very suspicious to me.
