I visit Colorado fairly often; most of my relatives live there. My CC permit is recognized there, so I have no problems with carrying concealed. From what I have read, open carry is ok everywhere except Denver. However, I don't recall noticing anyone carrying in the towns. Judging from your itinerary I would expect you should have no problems. I am rather cautious and would not open carry into most businesses in larger towns just to avoid any possible hassle. For some reason Durango strikes me as one place to be careful.
