Scandia Screamer in Ontario is one of my favorite steel coasters - The turns get tighter and tighter, with virtually no banking, and some pretty forceful drops.
Millennium Force has a section of track that unbolts - we saw it undone 4 days after the ride opened when it valleyed during testing - triggering the loudest "NOOOOOOOO!!!!" scream I've ever heard.
When I last worked there in 1999, Metro was on the "refurbishment" list - all that list is, is stuff that won't be operating.
Supervisors kept blabbing about Metro reopening, then, too.
