I shot this same tree about a month ago. At the time I mentioned that I thought it would look good with a sunrise illuminating it. The problem is that would require me not only getting up, but getting dressed, gathering my gear and then driving to the site. This is a major feat for me, especially on a day off. This past Saturday however I for some reason woke at 6:30 and managed to get over to it. My real motivation is that it is near my favorite coffee shop, Long Bottoms. The blue haze is from the fog that was present and  setting my white balance to the tungsten setting.
