CHICAGO — The NASCAR Chicago street race was shaping up to be a disaster.
After lightning cut part of Saturday’s programming short, a torrential rainstorm the next day submerged roads across the city — including the improvised downtown track that was set to host the main event and the end of the previous day’s race.
By 4 p.m. Sunday, three of the scheduled concerts had been canceled and NASCAR representatives began hinting of a refund system as the pace of the downpour worsened still, threatening the biggest race of the weekend: the Cup Series Grant Park 220.
