The rancho viejo development. Maybe closer to 5 miles outside of SF.

Based on the light levels we see 20 miles south of you, coming from SF, I wouldn't be surprised if you can't really see the Milky Way much. Come on down to the Galisteo Basin Preserve some night and see how it looks from there. Or, since I'm guessing you're at LANL, maybe just stay at the lab late one night :)

I’ll have to do that soon!

“Stay late at LANL” would imply I’m ever actually up there. I think I’ve been onsite 3 times since March.

There is the slight problem that the preserve technically closes at sunset :(

But maybe drive into the Cowboy Shack trailhead/parking near sunset, take a short hike so that it can get dark ... nobody's likely to complain.

And the moon is already rising later and later, making early-post-sunset viewing great again.
