9/16/01: Last Day For Viper At SFOG

First off, that ride model is no longer made, even when Anton was alive, they ceased production on the shuttle.
Why? Its a high-maintence ride with expensive parts (heck, the clutch alone back in 1990 was $15k when Kennwood replaced it to keep Laser Loop running 2 more months before its removal)

Secondly, a lot of parks don't want other parks problems like an old coaster.

So if I were Visionland or a small park thats not 100% financially stable, then I would shy away from a transaction like this.
