Six Flags had big plans for several of their parks to get major redesigns of their entrances which are long overdue. As usual they cut the budgets at the last minute.
Speaking of, there are rumors at Great Adventure of several rides being listed as "closed for the season" or have limited hours and days of operation posted. Supposedly it's part of across the board budget cuts by Six Flags. I wouldn't be surprised to see the same showing up at MM and I've heard the new ride is now on hold.
I'm guessing they have a bad quarterly report about to come out...
