spoiler: 46-across is an incredibly unfair clue, but i couldn't help myself. for the uninitiated... in 1999 chicago was awarded a civil engineering 'monument of the millennium' award for the genius feat of flooding the mississippi river and, thusly, st. louis, with our sewage. st. louis filed an injuction against the city for doing so and it went all the way to the supreme court, where they ruled in chicago's favor. die mad, losers!
