I can see the Flume at Towers lasting longer than both of those... Indeed, Depth Charge is completely out of place now at Thorpe, whilst if/when NWO gets removed and replaced by another coaster/rides, it will be similar to Corkscrew's removal...Log Flumes generally have a much longer life in comparison to coasters and flat rides, indeed, look at several American parks, and many still have log flumes that have lasted longer than Flume has even existed (Knott's for example opened in 1969 and still stands same goes for Magic Mountain's 1971 AND 1972 flumes)... So it goes to show that maintenance means a lot, and really, that's all that the Flume needs... Extra theming and a smoother ride... How? What? When?
