Who are the governing bodies of Quad Terrain racing and Utility Cross Country racing?

I've tried a google search with no luck. . .I got the names of the above series off of the Rath Racing website. . .and both of these series are apparently utility ATV XC racing series. . .I'm interested in this series and would like to learn more/possibly compete at some time in the very near future.

Thanks for your help guys!

OK. . .I found the GNCC utility classes but all of those events are East Coast races. . .I live in Washington so that does me absolutely no good whatsoever. . .I've looked at FantomZATV.com because they are a Northwest ATV event promoter but I didn't see any utility classes on their website. . .does anyone know of any Northwest utility ATV racing. . .preferably the XC/trail type races. . .I have no experience on a MX/quadcross/TT tracks and I don't have the money for a second racing only quad at this point in time.

Thanks,
