MR_SLIN#20 in California I found a spot like that in Death Valley when there was no moon out. It was so dark that I literally could not see my hand in front of my face, but the view of the stars was amazing.
Death Valley is one of the listed Dark Sky Parks, indeed. There are a few of them in the USA, seeing as you have quite vast national parks there.
For anyone else wondering if they're near a good place, you can find recognised reserves, parks and communities on the left side-bar here. The reserves are the most dedicated to low light pollution, but the parks are essentially naturally devoid of light pollution because they're far away from civilisation. As Mr Slin empirically confirmed, they are no less amazing places to visit. Have a look-see if there is one near you if you're interested. A lot of the Dark Sky Communities are near national parks and have all sorts of activities going on around astronomical events such as solstices and equinoxes, including night-time guided tours out in the parks.
