Six Flags Magic Mountain Tatsu Flying Coaster in Theme Parks, Roller Coasters, & Donkeys! Posted October 30, 2005 I went on Saturday after noon for fright fest. I couldn't believe the waits for the rides and the haunted houses where over a hr. or two hours or even more. This was the worst time I have every been to SFMM. Any way the consturtion is coming along very well.
