Cedar Rapids is very much like Grand Rapids in the way the river goes through the middle of the town. I never knew that they built the windows on the buildings that face the river out of aquarium grade glass but I'm sure they are glad that they did! Someone who worked there said water did find its way in some of the rooms at a slow rate of a trickle but it was very nerve wracking to work in one of those rooms and know the pressure of the water on the glass just outside!!
