Well I went to Chicago for the frist time in June. And I must say I was very pleased with the vast veriaty of sirens out there. Saw alot of T-135s a few cyclones and other sirens. One of the T-135s I deffently remember seeing was in Naperville. Can't remember the street. All and all had a good time. Oh and another thing I gained 10 pounds eating Chicago Stuffed Pizza my god that stuff rocks hahaaha
