I never remember being a huge fan of The Flume when it operated; it was perfectly OK, but I remember it being extremely long and not overly wet.
I personally found Congo River Rapids the more fun of the park’s two water rides by some distance, and seeing as Wicker Man is in my top 5 coasters, I certainly think it was a more than worthwhile replacement!
Logger’s Leap at Thorpe, on the other hand… now that’s a log flume I loved! I’m sure Exodus will be a more than fitting replacement, however; it looks like it’ll be a great ride!
