Does one's elevation above sea level change your perception of the sky? Thirty years ago or so, I camped out in Telluride, CO and saw moon shadows for the first time. I was surprised that they were so clear and distinct. They weren't the same back at home.
In my photos (and memory) the sky is a much more vivid blue than what I'm used to seeing here. I think I like the sky and clouds there much better.
Anyway, here are some photos from my trip last month. You can see others in my photo gallery.
I love the blue in the sky.

I was surprised to see cactus growing on the side of a mountain like that but it is pretty dry in the area. Anyway, I like the contrasting colors and textures in this one.
