Hah, tomfoolery at best. Knott's only has the following "preserved" in the park:
Stagecoach
Log Ride
Mine Ride
Chicken Dinner Restaurant
Ghost Town (in a sense)
The Little Red Schoolhouse (Which was painted PURPLE before I left)
Denver Rio Grande Western & Southern locos and rolling stock
Independence Hall
Stuff that is still kinda there, but not really:
Pan For Gold (moved to make way for GhostRider)
Church of Reflections (demolished and built outside the park, not the same structure)
Sky Cabin (closed, and Parachute Jump removed)
Roaring 20's (the sign is still there, but that's about it)
Fiesta Village (NONE of the original attractions except Montezooma's Revenge are left)
And then of course, stuff that is LONG GONE:
"El Camino Real" Mission Dioramas
Volcano
Haunted Shack (removed for Vertigo! Which was removed for Screamin' Swing)
Wacky Soap Box Racers/Motorcycle Chase (Windjammer replaced, followed by Xcelerator)
Gasoline Alley (Same above)
Henry's Auto Livery (Same above)
Cable Cars (Parking lot area, removed)
Jungle Island (See below)
Adventure Island (now "Knott's Lagoon" but nothing is left of the original park)
Beary Tales/KoD
Mule Train (Relocated to parking lot, then removed for picnic grounds)
The original attractions of Fiesta Village (left with Bud Hurlbut)
Dolphin Show (Perilous Plunge took its place)
The ORIGINAL
Berry Stand (Was around for AGES...it was taken out, blasphemous!)
The adjoining Boysenberry Patches/Bushes
So I mean, even counting the stuff that's kinda/sorta there, we're talking 10 or 11 historic Knott's Berry Farm icons still standing, but 15 historic parts of Knott's are also gone. And some of these things removed were entire lands, or integral to Knott's Berry Farm, such as the Original Berry Stand.
