I went on all three rides.  Insanity was first.  It's a machine that dangles you three football fields above Las Vegas and then spins you around for a little.  Then next was X-Scream, which simulates a roller coaster pitching over the side of the building (perhaps an homage to their older roller coaster?).  Both are \"exhilarating\", similar to narrowly avoiding an errant dumptruck when riding your bicycle, or having a guy with his gun out give you a lot of trouble then leave.  There is also a freefall ride, which is totally limp-dicked compared to the other two.\n\nFive stars because two of the rides are just shockingly frightening.  State of the art.
