I recently stayed at Camp Blackman for a couple of nights and it was nice and dark there, I was fortunate enough to have considerate campers around me that went to bed just after darkness fell
The horizon is OK there in most directions, although there are a couple of small hills intruding in the N and NE directions. How much depends on where you setup camp. There was no discernible sky glow in any direction that I could tell.
There is the risk of a camp fire making for a smoke stack and I don't recall seeing anything posted anywhere about considerate use of light at night, so I considered myself lucky...
