I have gone to North Center Ribfest since moving back to the city in 2008. Until 2018 I even brought Parker most years, when he could walk 60 blocks as easily as I can. (Now he has trouble walking four.) I also attended the smaller, less-well-run Windy City Ribfest a couple of times. The Chamber for Uptown just cancelled this year's Windy City Ribfest, and the North Center Chamber of Commerce cancelled their Ribfest two weeks ago.
In honor of both events, I will have full slabs on both weekends (June 12th and July 3rd).
So far, Naperville's Ribfest (actually held in Romeoville) still plans to go forward on July 2nd. Maybe there will be rib samplers this year after all?
