Trust me, SFMM is horrible. Yeah, they have some great rides, but others are hyped up average rides. (EX: Superman, X). The day I went there, only one side of Collosus was open (its their racing woodie), and the other side looked to be in disrepair. Heck, even the trains on the other side had what looked to be holes patched up with duct tape! Flashback wasn't even open!
EDIT: I just looked at RCDB, and it said, "The Flashback is generally closed from May to September." Why have a ride only open in the winter?
