The little arch on this "gateway" to the riverfront in Clarksville says, "Touch the Mississippi."  Undoubtedly a more attractive prospect when the Mississippi isn't intent on touching you and the town around you.

To prepare for floods, the town places sandbags everywhere, that that's not enough.  I'm told that sinks are disconnected; toilets removed; and special plugs are used to cap pipes and drains. 

The cafe where I had breakfast faced the river and escaped the surface inundation.  Unfortunately the plug capping the men's toilet drain didn't hold, and the place was flooded.  When the water retreated, six inches of sand covered the floors and several live fish  flapped between tables.
