I understand that Riverfront in Marysville is currently building a quad mx track!
Apparently the support for quad only Saturdays was encouraging enough to build a quad only track.
I'm told it should be ready by November. Nor Cal riders should try to support this effort, as most private mx tracks are not that open to allowing quad riders.

 

Hello "notsoyounganymore" I just joined this site and ran into forum. YES count me in my friend. As a matter of fact I will be going up this Saturday 4/26/08. I've been trying to find out if it was ever opened. Now I know and will be ther for support. I really don't mind the drive from Salinas,hey anything to help support atv riding. I hope to meet you out there. It will be my first time on the track, I reall y hope I like it because I enjoy riding on tracks. I own a red Arctic Cat dvx 400. Hope you don't read this to late. Peace my friend; don't stop ridng.
