Early morning is always filled with vibrant colors. Here's a great shot of a USAF Thunderbird F-16 in the early morning hours.
As a side note, I'm off to San Francisco again this week. Always a fun city to visit with great food and spectacular views (too bad I'm going there for work).
On another note, I'm working on a photo book filled with the best shots from the site over the last year. It might end up being a little pricey, but I'm hoping some of you will appreciate it.
