I agree on the 3ds! That's why I'm trying to pace things the way I am, so that you don't feel rushed. Everything looks great so far, but I've been watching your own park spring up, and I certainly would want to be working on that too if I were you!
Also, I'm doing those years first since I bet that's where the most interest is, but I might do a 1978 and 1984 version of the park too, and include Das Katzchen, Die Wildkatze, and Glissade.
Also, I'd be shocked to see any coasters removed from Busch, as the only thing that would make sense to remove is Loch Ness, and considering most agree that's one of the best, smoothest Arrow's in the world, I'd be VERY shocked and disappointed to see it go. I mostly said that in jest! Then again, I was VERY shocked to hear the news when wolf was getting the ax, as that was one of the best arrow suspended coasters in the world. There had been rumors for years of Wolf taking a year off to get overhauled and upgraded for longevity, but considering the timing of Wolf closing and the park selling, I think the new company had no interest in those upgrades and decided to tear it down instead :/ Verbolten is a cool ride, but I would have preferred it on the Drachen Fire site and kept the Wolf alive! I was also perturbed that the excuse they gave the public for Wolf closing is that Arrow recommended a 25 year shelf life on their coasters. Yeah, that's a pretty lame reason in and of itself, especially considering the almost 40 year old Arrow sitting there
in the same park
