There's talk about a per person fee but it will probably never happen. The thing at Gold Creek is different, they're selling passes electronically to make it easier to buy, but they're still good for parking and not related to how many people are on the trail. They're doing this because people who don't buy a pass and then get a ticket, aren't funding the program the ticket money just goes where all parking tickets go, so if they can sell passes instead of writing tickets that puts them in a good place.
