Gary, IN: how dark is the sky here?

Suburban
25.2 nW/cm2/sr

Gary reads as suburban on this dataset's scale. Light dome dominates much of the sky. Only the brightest stars and planets stand out clearly. Gary's sky is brighter than 56.8% of the 3,206 cities in this dataset.

This comes from a satellite measuring light radiating upward, not a person's eyes on the ground, so it isn't the same as a Bortle class, though the two track each other closely - see the Bortle scale guide for where they can disagree.

How far Gary is from a meaningfully darker sky

Lake Station, IN, about 5 miles away as the crow flies, measures in the suburban edge band, one step darker than Gary. Actual driving distance will run longer than that straight-line figure.

Lake Station, IN is itself still a measured city, not a designated dark-sky park, this only compares against the 3,206 places this dataset covers.
