Dom,I too am from Illinois. The northern suburbs of Chicago and I have no local ordinances that I know of prohibiting the use of airguns. Now I am very good friends with the commander of the police department so that doesn't hurt if something ever were to happen lol. I would recommend calling as well because the website isn't very helpful in my opinion. I do know that you can pretty much hunt your own land and private property with permission from the owner as long as it is legal to discharge an air rifle in the county or city that the property is in. Let us know what you find out. I really don't do much hunting outside of my back yard but I would still like to know for future reference.Good Luck and Go Bears!
