Located about 30 miles from the center of Chicago is Homer Glen, the newest International Dark Sky Community. Homer Glen joins an elite group of just four such places in the world - Flagstaff Arizona, Borrego Springs California and the Isle of Sark in the UK.
The skies over Homer Glen are not as dark as they are in the other three places but the community takes outdoor lighting very seriously. Seriously enough to warrant them the honor. The people of Homer Glen have worked to make a difference in outdoor lighting. You can too.
