Okay, the 90's were considered by many to be the "Third Golden Age", at the the end of the other "Golden Ages", what happened? They ended, I think the turning point for parks in this Golden Age happened with 9-11. But amusement parks, like anything else go through cycles of good and bad. We are probably going to lose alot more parks. But it happens! Don't worry about what you cannot control. Most parks today will probably not be here in fifty years.
My predictions for park losses in the next fifty years:
1.Knott's Berry Farm
2.Paramount's Great America
3.Six Flags Magic Mountain
4.Belmont Park
5. Santa Cruz Beach Boardwalk
6.The Adventuredome
7.Six Flags America
8.Enchanted Village, Wild Waves
9. Conneaut Lake
10. Frontier City
11. Sesame Place
12.Lakeside
13.Six Flags Elitch Gardens
14.Lagoon
15.All of what is left of Coney Island
16.The Great Escape
17.Six Flags Darien Lake
18. Cypress Gardens
19.Joyland
20.Legoland California
Thats all I can think of for now, all of these parks have fatal flaws somewhere and while I will miss them, alot of them are ghetto and/or crappy. But so what they aren't closing tomarrow and you don't worry about what you cannot control.
