Searching for horizon lines can be difficult when you're surrounded by hills and buildings.   Learning to appreciate the shapes of those hills and buildings against the vastness of the sky is a saver of sanity during days of chaos for me.  Where land and buildings intersect with the expanses of cloud and atmosphere is a sweet spot for me in my work.  How can they coexist: feel comforting but still wild; stationary but still dynamic and moving?  Where's the light headed?
