Speaking of Maintenance at Six Flag's, all I hear is bad things about it. Here is a piece of journalism I found about the River Raft Ride at SFOT.
http://www.fwweekly.com/archives/June_17_1999/cover.shtml The reporter did site sources, and even found the former Maintenance worker for the ride. It appears to be a solid piece of journalism, a nice lead included. Though you are supposed to show an unbiased point of view in reporting, this guy has a side. It is the longest article I have ever seen on an accident.
If the article is true, then it just shows how Lackadaisical SF has become on the subject of Maintenance. Firing experienced employee's for probably cheeper one's and poor operator training is no good. Just the thing I want when I am drowning, someone telling a lifeguard not to get in.
