I have always wanted to ask this but does anyone have further details on why the Vampire was modified in 2001? I understand it was experiencing a lot of downtime but why exactly? Other parks still have Arrow suspendeds in operation - why wasn't it possible to fix the problems instead of modifying it to such an extent to what we have today? And why was the tunnel's length was halved? I remember riding it on a hot day and the tunnel's temperature was noticeably cooler to the outside temperature because is was so long and dark, it really did feel like you were flying into a cave. Why, why, why!?
