Chicago is the third largest city in the United States. We have numerous golf courses in and around the city but no indoor driving ranges. These are necessary as Chicago experiences extremely cold winters and extremely hot summers. Golfers tend to visit other warmer states when trying to golf or work on their game. As a fellow golfer, for 15 years, I have experienced the same issue. The solution is an indoor driving range facility that provides state of the driving range putting greens as well as instructional golf stimulation machines all inside the comfy climate controlled dome.
