Hey phsnthntr,
I'm in Crested Butte. Not quite the western slope, but I have a Vizsla and enjoy getting him out to chase the wiley rooster as often as I can. I usually have time constraints that don't allow me to travel out of state very often. As a result I belong to a gun club in Delta (BCWC). This is the only way I can get my dog on birds on a more regular basis. Their facility is great and the birds are strong. My dog doesn't care if the birds are released or not, and the large flight pens allow for very strong birds.
Good Hunting!
Paul
