If you think we talk too much about the current and expected repairs on the Vincennes Levee, I suggest you take a walk along the Levee - especially when the river is high. Think about that dirty water, mud, and whatever else is in there not only in most of our basements, but in the hospital, Vincennes University, many retail stores, chuches, and most of the historic sites.
If you think most of town is above the river, take a look at the heights of various parts of town on Google Earth and compare them with the level of the river also available on Google Earth. Add ten to twenty feet to that number and compare the heights.
If there's one thing most of us need in Vincennes is the Levee.
