Imagine what its like to live here. Actually, I live in the better part of Jersey, except during summer with all the NYC trash clogging my roads and trashing my beach.
Anyway, the Jersey Great Adventure really is dirty, lines are huge, only 1/2 of the rides work on any given day, and the quality of people are really lower class. I went to Busch Gardens in Williamsburg, VA, then the next week went to Six Flags. Luckily, my friends still work there, so I go for free, and thats the only way I will ever go again.
But, if you do choose to go, let the NJ forum know and make the best out of it.
