Lakeland, TN: how dark is the sky here?
Lakeland reads as suburban edge on this dataset's scale. A noticeable glow near the horizon. Brighter stars and constellations are easy to pick out; the Milky Way is washed out. Lakeland's sky is brighter than 13.5% 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.
