Just for accuracy, Six Flags, and any amusement park, must be posted to be off limits. The ban on amusement parks has been modified to require you be given 30.06 notice.

But, Six Flags corporation is so anti-gun, they tried to stop off duty officers from carrying in the parks about 10 years ago. I am fairly sure they are properly posted but I can't swear to it. I stopped being willing to pay their prices a long time ago too.
