到 St. Luis 當然就要去 Gateway Arch，裡面和二十五年前改變很多，裡面多了一個博物館和那個討人厭的強迫照相。之後到對面的 Malcolm W. Martin Memorial Park。
前往 Chicago 之前，經過 Illinois 州府 Springfield，並在 Portillo’s Hot Dogs 吃了簡餐。
在手機上發現 Lincoln Library，順著指示發現根本是 Springfield 市內的圖書館，孩子眼尖看到圖書館旁的 Lincoln Home National Historic Site，之後再前往 Lincoln Tomb。
又繞道 University of Illinois at Champaign Urbana，最後才在傍晚八點半時到了 Çhicago 的外圍城市 Monee。
夜宿 Quality Inn Monee I-57。
