Come the morning of September 4th, Hydro at Oakwood will be an only child. Knott's Berry Farm have confirmed they plan to remove Perilous Plunge after Labor Day, the only other Intamin River Plunge in the world. I absolutely adored Hydro when I rode it, and was eagerly looking forward to PP. But for some reason, when I rode it in 2009, it was just incredibly painful and boring - nothing at all like I remember Hydro. Maybe it's because I'd grown (I visited Oakwood in 2005) and the restraints didn't fit me anymore. Or maybe it was something different with the ride. It did have a different layout. Anyway, bon voyage Perilous Plunge, don't speak ill of the dead and all that. Screamscape reckons they'll replace it with a giga coaster, similar to Skyrush.
