I remember on a weekday fright night (in 2009 or 10 I think) it was pretty much walk-on and whatever setting it was on was completely insane, that's the one ride on Samurai I've had that's always stuck in my mind, it's such a shame it's never like that anymore
Also miss the mist in 2008 FN that was so dense it was floating up to the fasttrack booth under Colossus, I never went on any other rides apart from Loggers, Rumba & Flying fish (as I was a scaredy then) but the atmosphere around the ride that night was great
