Don't feel like the Lone Ranger, they sent me one back in the 70s and I had never been there in my life at that point.
They just pick out random numbers from a data base and mail out tickets. Some people actually pay them and Chicago rakes in the bucks.
Holy Cow, amazing they sent you a ticket while you had never been there. You should have seen the letter I wrote to them...I called them everything from running a banana republic to a crooked bunch of thugs. You are right, some people pay any bill that is mailed to them.
