I could add my 2 1/2 cents worth here as I lived in CO and go back there often. But you have gotten some good info. Thom is the go to guy for CO these days but 2gypsies has good info. Actually, most everyone does.
As far as Estes is concerned, I lived there 8 years and just last week shared time with a very long friend who talked me into living there back in the early 90's. They still live there. The town is a real mess as town itself but with all the people who get to Rocky and show no respect for anything. The town is got very bad management (Mayor in particular) and let's just say politics which if affecting a whole lot there......including visitors. Fees for Rocky have gone way up and many new restrictions. My recommendation - stay the heck otta there. Go done to the San Juans around Buena Vista for someplace - we will be in B V for a month again this summer.
I rambled but just do some good checking on things.
Be safe and God bless.
