On mornings of most school days, the City of Davenport sets up a mobile speed camera at the corner of either E. 28th or E. 29th and Jersey Ridge, across from Eisenhower School. They enforce the 25 mph school zone rigidly (as they should). But people coming down the hill from the south on Jersey Ridge are usually upon the school zone so quickly that they’re easily doing 15 over and the cop takes their picture.
