Here in OKC it has been over 100 for several days now (and more to come). My wife and I have a trip planned to northern Colorado (thank God) in about two weeks. My primary photo interest is ghost towns, old mining sites and equipment, and mountain scenes. With that in mind, does anyone have any suggestions for photos near Denver and north of Denver? We are going to spend a day or so at Estes Park, then work our way south to Black Hawk and Central City. We are also planning to stop in Georgetown and Leadville. Any other suggestions or ideas? Please advise.
