Since it was mentioned...
The Trabant vanished before the 1991 season. That same year, the Scrambler moved slightly.
Schwabinchen moved to her current home in 1985 when Avalanche Run was constructed. That was also when the Wildcat moved, and the Rotor and the Bayern Kurve went away.
What I don't rightly remember were two dates associated with the Satellite Jets. For me, they were *always* back by the Blue Streak, about where the Calypso is now...but I remember at one point they switched from the side-by-side jets to the in-line jets, but I don't remember when...and I remember there was one year when I was really mad 'cause they took 'em out entirely...
