To be as clear as I can, BLM land enjoys very little protection or management for recreational use--the land is up for grabs. When the state takes over management the level of protection rises markedly. Of course, this includes protection against boondockers trespassing there without paying, which is the point of the original post.
Those who are complaining about higher fees have lost sight of the larger picture: As more people and/or businesses compete for use of a declining portfolio of public lands, compromises will have to be made to get any share of this. Higher fees in exchange for a clear recreational land-use mandate by the state is just such a compromise.
If we refuse to compromise with an entity as benign to camping as the state parks--and instead insist on squatter's rights--we are picking a fight with one of the few agencies that is on our side. This is self-defeating.
