They always say "have a Six Flags day!" as you're leaving, at least at most locations. I haven't the slightest clue what that means. It sounds so stupid that I actually like it.
So I guess you had a Six Flags day!
I just have to say that the clientele at Great Adventure has noticeably improved over the last decade or two. Of course it depends on when you visit (don't go to the summer concert series!) but on a random Saturday you are sure to find a nice family-friendly environment now. At one point, it was a place that families with young children dare not visit, and I'm honestly not sure how that mentality began to change, but it has.
I'm fact, I don't know if you all are aware, but Six Flags Great Adventure recently stole Animal Kingdom's title as the world's largest theme/amusement park. They have a safari that, before 2013, was separate from the park. People had to drive their own vehicles through. The monkeys climbed on the cars, and animals liked to attack the windows. Good ol' fun! But in 2013, they turned it into a ride within the park (like DAK's, theming aside), so that bumped them ahead of DAK in acreage.
So while Magic Mountain may still suck (I've never been so I can't say), I'm feeling slightly optimistic lately about my home park. Maintenance and theming are still very very hit or miss, mostly miss. And of course it's nowhere near the level of Disney and Universal. But it's a significantly better place than it was two decades ago.
