not sure when things changed, but it was new to me. when i got my camping reservation on the internet, i knew to go to the reservation office to get things in order etc, but when i did, they said they do it different now. instead of having to report to the office to get your campsite, all you have to do is show up at the campsite and talk to the gate employee to get in. you don't even have to have your printed reciept from the internet, just simply show your I.D. and that's it. they already have a list of who is reserved right there. pretty simple and sweet if you ask me.
i had forgotten my reciept at home and thought it would cause problems but it didn't matter one bit.
