Out of interest, as a foreigner/outsider in this and therefore not aware of some of the cultural sensitivity...

Why isn't price used more as a tool for demand control? On the one hand we have an underfunded park service, and on the other, massive demand for the resource.

I'm not talking about further restrictions, but would releasing some small extra capacity at a (very) high fee more than compensate for the extra resource damage involved?

Or does this kind of stuff just result in a further funding cut, so it no longer becomes incremental and it just becomes part of the overall revenue?
