No, honestly, I really truly believe that it has to do with latitude more than anything else. I have lived in cities, I've been in the country. I can look out my window now and I feel like I can reach up and touch the clouds and the sky. They are lower, more closed in, closer. In California, even in the heart of downtown LA, or amongst rows and rows of apartment complexes, in areas where building were taller and more tightly packed than the terraced rows here, I never, ever, felt the sky was as close as it feels here, or as small. Did the clouds ride higher there? I don't know; but I do think that the curvature of the earth and where you are on it has a lot to do with it.
