Destiny USA, and Carousel Center before it, could not have “happened” anywhere else but here. And not just here, in Syracuse, but on the frothy, stinking shores of Onondaga Lake. If it wasn’t the most polluted lake in the country, if it didn’t sit smack in the middle of a Rust Belt city verging on bankruptcy, Congel would have neither abandoned land to grab nor the political leverage to exploit it. Had he hawked his megamall to any community located on any of the other Finger Lakes — the affluent resort town of Skaneateles, say, where the Congel clan owns multimillion-dollar mansions — they would’ve told him to take a hike.
