They call it an annual permit.
They know and we know, that we will only be here for the day, and need to park one time only. To call it a annual parking permit and charge $11, is thinly disguised fraud for a couple of hours parking. It is sad to think that a government agency is willing to damage public trust so readily.
You would think that a National monument would be a place of honor and trust, that is available for all to view at a reasonable cost and be free from deception that is designed to gather our dollars.
