Is it your intention to list all rollercoasters that no longer exist or have been moved?
I would like you to so I can include them in my Track Record.
I think what I might do is add some means to add dead coasters, because I really don't have a lot of interest in adding hundreds of defunct rides, namely because it's so difficult to have complete records (stats) in the database on these rides. However, if you'd like I'd encourage you to add them in the contribute section.
