Original Gold Rush Express - Six Gun City

Hi all,

I've been doing some poking around looking for information on why Six Gun City pulled out the original Gold Rush Express (Wisdom Runaway Trail model) after only a month or so in operation in 2004. Does anyone know any of the background on this?

All I've been able to find is a cryptic "it never worked right" on another site.

Any additional info would be helpful. Thanks!
