Gordon's House/Judge's Car Explosion Location?

[riskproductions]

Hey everyone, a little help if you could. I am heading up to Chicago this Sunday to tour all the filming locations. I have them all documented, but I can't find the neighborhood where they blew up the judges car. I think in the back is also where Gordon's front door was. I was there a week after they filmed it, but now I don't remember where it was. If anyone knows it would be appreciated. Thanks!
