How dark is it, really?
Dark enough to see the Milky Way overhead on a clear night, though glow from nearby towns washes out the sky near the horizon. (For the detail-minded: Bortle class 4, an estimate.)
When should I go?
Pick a night when the moon is down. The next stretch of moonless evenings is Nov 5–12.
