When I started working for the forest service, the Forest I was on had 6 people working in the lands department. They do special use permits, right-of-ways, land exchanges and acquisition, water rights, and anything else that had to do with land use laws. When I retired there were 2 people there and one of them spent 100% of his time dealing with everything involved in a proposed gas pipeline that would be crossing public lands. Three years before I retired there was only 1 person, but he was lucky enough to have money in his budget to hire someone for six months to help. The guy that took that job was in my survey department and wanted to broaden his horizons by trying new things. He later told me that he spent the whole six months doing nothing but issuing and inspecting special use permits. So, it is a full-time job done by a person that can only devote a small fraction of his time to doing it.Ask Brian "Gritty" Call about not getting filming permits.
Wish enforcement was a lot tighter, but given the budgets these entities are working with, I can't blame them.
