Sam,
I'm sure that Mike Lockner will chime in here soon (President of the Rocky Mountain Chapter). I would think that since it is called the "Rocky Mountain" chapter, that would include your area as well. I know that a lot of our Colorado Power Stroke Club members get together from time to time way down south (I can't always make it) and I am always trying to schedule events down that way as well.
I will keep you all informed when we have events scheduled down your way, and I am sure that Mike will too. In fact, I am trying to schedule one down in Alamosa (way south, huh?) soon (mod/dyno day) and we have had a few things in the Springs. It just seems like Denver is a pretty good central location for us all.
Just plan a get together, invite everyone and you will be amazed at who all shows up. These Dodge guys have never let me down!
