How did we miss this?

For a number of years, Six Flags has been hosting (for money, for money) a Muslim Youth Day event. Like other such sponsored Days, they close the park to unbelievers (sorry, other patrons), giving the attendees a day free of non-Islamic influence.

Note the halal food and "dress modestly" admonitions; it wouldn't do to eat something unblessed (what is trayf in Arabic?) or see some skin; even going to Six Flags isn't worth going to hell...
