https://media-cdn.tripadvisor.com/me...a/exterior.jpg Courtyard Marriot did a great job on this old John Deere building in Waterloo. Main clock house was on the corner of it. I used to go in ride to fifth floor walk across an overhead enclosed alley to the building upstairs up to 6th floor. These buildings were built like tanks, they had a heck of a time demolishing some of the other buildings. 2 remain.
