There are basically 4 in Colorado and they are kind of listed on the CD website that the coloradomultigunlink takes you to.
Weld is Zak's match on the 4th Saturday. One shotgun stage, 3 rifle pistol stages. Zak will make you do some odd stuff.
Lake George is also the 4th Saturday.
I run the matches out at Colorado Rifle Club in Byers (done for 2012). Feb 22 will be run & gun with .22rf on steel. March is a standard 3Gun match, April 4-7 is the Area 2 Noveske Multi-Gun Championship. Then we will have a one stage, 4 gun match on May 4th. Jun 1, Jul 1, Oct 5 are normal 3Gun matches. We use USPSA time-plus sanctioned rules.
Then the Johnson's run matches at Raton (done for 2012)
