Though it was mostly a foggy and overacast day at the top of Clingman's Dome (on Oct 23, 2006), I caught this shot showing just a little bit of blue sky, thanks to a break in the clouds. There were a few breaks in the clouds and they moved by pretty fast. After one snap of the shutter, the sky turned gray again. It was so cold and windy, no wonder the clouds were moving fast.
