NASCAR made history on Saturday in Chicago, with the first-ever street race on the iconic stock car racing circuit.

While the NASCAR Xfinity Series Loop 121 on Saturday was ultimately postponed (to Sunday morning at 10 a.m.) on lap 26 of 55 because of lightning in the area, fans still got the chance to take in world-class racing in Grant Park.

From racing to concerts by the JC Brooks Band and the Black Crowes (a late-evening show by The Chainsmokers was cancelled due to weather) to food and more, Chicago and NASCAR made quite a pair on this steamy summer day.

Here’s a look at some of the day’s highlights:
