I bought my first annual pass to Knotts in July 2005, and it's true, the charm that used to be at Knotts is no longer there. Once I saw they took out the Haunted Shack, the rest just went down hill.
Don't get me wrong, I still enjoy going because it's just different and usually not crowded as much as Disneyland. I like the ice skating stage shows they have during the holidays and summer months, and watching the show at the Calico Saloon.
I still think Knotts has charm, but it's now ghetto charm!
At least their annual passes are still under $100, that's nice too!
