Here are some photos on the way up to and around the old mining/new casino town of Central City.
Then, we drove over to the Red Rocks Amphitheater where U2 performed their landmark concert performance of Sunday Bloody Sunday in June 1983 which they recorded and made them legends of rock and roll.
The clouds, blue skies, and red rocks were spectacular. The next picture is a camera "oops" but I kind of like it of the clouds reflected in the car windshield.
Here's a model of the amphitheater. There is also a gift shop and a Music Hall of Legends for viewing.
During the day, the amphitheater and the surrounding parklands are available for recreational use and boy, are they used! Plus, there are no parking or day use fees. Here is a zoom-in photo of downtown Denver.
Unfortunately, I was in no shape to work out, hobbling around on my crutches.
And here's the classis U2 video with a little intro. Enjoy!
