The Spider is no longer allowed to be run in manual mode, it can only be used in program 4. And I've been told that underneath the external structure it is a travelling ride. There is music on it, and we can choose what we like to play on it as long as there is no swearing. The actual limitations are "Fun, Family Oriented and Luna Parkish". Whatever Luna Parkish means....
And as to not going on the Ranger.. The harnesses aren't a problem any more to my knowledge, although it did open on a child once when I was operating. He wasn't hurt but I was a little shaken. My concern with the Ranger is more to do with the motors. There are supposed to be 4 operating motors on the Ranger. There are less than that. You can hear the bastard struggle to lift even a half load (20 people). I'm not a maintainance guy, I just operate but there is something wrong with it. BTW don't sit on the right hand side, second row from the back, second seat from the entry.
