In the Northeast, Cherry Springs State Park in PA as someone else mentioned. Out in the Mountain West, anywhere remote will do. Partial to Yellowstone myself.

In California, the east slope of the Sierras is pretty dark in most places. Even Yosemite is not terrible, though the light pollution from Fresno is noticeable.
