One thing we may all need to keep an eye this summer, regarding campgrounds in the Interior of the state, is the major military project to upgrade the radar units at Clear Air Force Station. Clear is located between Healy an Nenana, next door to Anderson on the Parks highway.
The military has allocated $1 billion ( yes that's a B) for the project, five years to completion and a work force of 2,500. If most of the workers were to bring their families, it could be a total of up to 10,000 new residents scattered between Cantwell and Fairbanks. I understand they are currently building a 500 person (how's that for being politically correct) LOL work camp at the base. Clear is considered by the military to be a remote base, so there is no family housing on base. But I would suppect that with it being such a long multi year project, that many of the civilian workers will bring their families with them.
Trackrig, who is currently back home in Anchorage, may have more and better information than I have available. His father worked at Clear AFS many years ago and Anderson was where he grew up. Bill (Trackrig) and I have several mutual friends in the area, some currently working as civilians at Clear. I know he was recently motor homing with some in Las Vagas so may have more info.
Not sure when the major labor force will show up, but it could cause crowded or full campgrounds, perhaps starting this summer or the next one.
