“The agency knows who they are, fire them and their immediate superiors to show you mean business.”
The upper echelon within the NPS likely knows who is doing it, and probably before it’s even done. They will never be fired unless forced to do so.
The NPS is a total green outfit. The day and age of the tourist friendly ranger packing a chainsaw on horseback is gone. The Clinton administration started hiring greenies, and that batch is now high enough on the ladder to be running the Badlands park.
The info in the latter paragraph I know for fact.
Compared to typical state parks, the NPS is a disaster in terms of facilities. I say turn over all federal parks to their respective states for management with existing federal dollars and hire all new help.
