Monroe, WI: how dark is the sky here?

Satellite radiance puts Monroe in the suburban band. Light dome dominates much of the sky. Only the brightest stars and planets stand out clearly. Only 54.4% of the 3,206 cities measured here read darker than Monroe.

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.

How far Monroe is from a meaningfully darker sky

Freeport, IL, about 22 miles away as the crow flies, measures in the suburban edge band, one step darker than Monroe. Actual driving distance will run longer than that straight-line figure.

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