OMG!!!!!
You gotta ride Superman: Ride of Steel -
BEST DAMNED STEEL COASTER IN THE COUNTRY!!
Then you gotta ride Superman: Ride of Steel, AGAIN...
Seriously, backrow of S:RoS is the greatest steel coaster experience, it's like airtime nirvana.
Pandemonium is a fun spinning coaster, and Mind Eraser is appropriately named - it's a Vekoma SLC (Suspended Looping Coaster), with a reputation for being rough on the head and/or testicles.
Don't miss out on some of the smaller stuff, like Houdini's Great Escape (It's a fun "illusion" that's a modern version of an old "Mystery House" attraction)
Not a great park, but not a dump like Six Flags Magic Mountain has become.
