Almost two years ago I paid the fee out of my own pocket for Per's Zion gathering. It is not new, but has been given more teeth. This is in regards to commercial enterprises such as movies, commercials, and workshops/gatherings where it is organized for the express purpose of photography. I paid $200 at the time. If it had been spread out over everyone who attended it would have been less than $10 each.

Given that congress has slashed a lot of the budget for maintaing the parks, it is no surprise that the parks are trying to find ways to replace those funds they desperately need.
