Don't they already have this? Not my screenshot but it looks like they have a way to show closed rides already:Hopefully there are plans to roll out a significant website overhaul of all of the Cedar Fair and Six Flags parks that will provide better ways for parks to communicate ride status. Right now they just really don't seem to have a good way to do that.
Sounds like they don't want to show too many closed rides at once. The flipside is when things are removed, that's when rumors start up.
