I went down to the Grand Canyon Friday afternoon with clear skies in Vegas. As I got closer to the canyon the clouds were increasing. By the time I found a place to pith my tent there was 90% cloud cover. I set up 2 cameras anyway on the hopes it would clear up. Right around 11:30 there was a break in the clouds and I managed to get about an hour and a half of shooting time.
