Maybe I'm way too cynical, but I think having you decide not to visit national parks is part of the "game"*:

  1) make it unpleasant to visit a national park
  2) say: "see, no one visits national parks, we should privatize them"
  3) profit!

Yes, this is galling, but lawyers joke about the kind of client who would kill his own parents and then throw himself on the mercy of the court as an orphan.

* the game as described by Eric Arthur Blair:

> O’Brien: How does one man assert his power over another, Winston?

> Winston: By making him suffer.

> O’Brien: Exactly. By making him suffer. Obedience is not enough. Unless he is suffering, how can you be sure that he is obeying your will and not his own?
