Welcome to Zion?

Zion National Park is proposing yet another rate increase for access to the park. It is already the most expensive park to visit in the state. And while most will pay it, including myself, I have to ask: what happens to people who can't? Are they not welcome in our National Parks anymore? These are public lands, not private entities, and while I understand that it takes a lot of money to run a park and keep things in the park maintained, I worry that National Parks will become a place that only the elite can visit. In reality, it is the poorest and most beleaguered among us that would benefit most from contact with the natural world.
