Much ado has been made about how the forlorn wreck of the USS Inaugural, a minesweeper that survived World War II only to sink in the Mississippi in the Great Flood of 1993, is now easily viewable just south of the Macarthur Bridge.
It is worth checking out, in what can be best described as a legally ambiguous location; who owns this stretch of the riverfront? There are no signs to aid in the determination of this fact.
As such, you just need to climb over a mound of detritus, and the wreck is right there in front of you; just look for the break in the flood wall at Rutger Street.
Looming just across the river is the giant Cahokia Power Station, sitting in splendid isolation on the Illinois riverbank.
