There's a DarkSkyโข park a few hours from me, I don't know how it got on that list, probably bribes?
Reason I think that, is there's a H U G E suspension bridge visible from the park that's lit up like an airport runway all night long, casting terrible light pollution into the sky and surroundings.
So, my advice - don't worry about finding a DarkSkyโข listed park. Use a map and find a remote site that's also close to things you would like to do during the day time.
Big things to consider, where is the closest mega city, and the closest mega airport?
Mega cities will destroy the horizon, I don't think a truly dark horizon exists anywhere in the lower 48 anymore. The more mega, the higher up from the horizon they destroy.
Mega airports, why? When you're camping in a very remote location it is so quiet that you actually hear the noise from the jets even though they're a long ways away. It sounds quite loud surprisingly, since your brain has no reference to scale the volume.
