Yes. I've been booking back country camping and trail access for a couple of years now and at no time did I suspect the money was going anywhere other than the National Park Service and BLM to support the programs and sites. I never would have imagined significant amounts, in some cases the majority of funds collected at a .gov park service site was going to a for profit defense contractor. In fact the site states in places that fees go to support the parks. No where does it say fees go to support for profit defense contractors.
