The Gas Tank

I can't believe that I got this!! I had little time to "get a blip" today. Choices were: pile of mulch, traffic. some building...
Then I remembered that I would be passing this gas tank on the expressway. It was one my step-father photographed many years ago and I have always liked it.
Traffic was pretty heavy so I just stuck my hand out the window and took a bunch of shots. Most were as I expected...then I saw this one!
Score!
I like how the foreground is blurred and the tank is clear. You can see the profile of a Chinese man in the blue strips and a horse in the orange one.
