Well I did a search, but couldn't find that anybody else has heard about this. Maybe it's not supposed to leak yet? I dunno, either way, I heard (from a reasonably good source... somebody who is a former employee and is in touch with many managers at Wonderland) that if attendance and sales are up at Canada's Wonderland this year, Cedar Fair is considering adding a Top Thrill Dragster to the park.
Again, don't rely on this too much, because it's just a possibility (and obviously a rumour), but I think it would be a great addition to Wonderland.
